GENERAL DESCRIPTION
The ADGM1004 is a wideband, single-pole, four-throw (SP4T)
switch fabricated using Analog Devices, Inc., microelectro-
mechanical system (MEMS) switch technology. This technology
enables a small form factor, wide RF bandwidth, highly linear, low
insertion loss switch that is operational from 0 Hz/dc to 13 GHz,
making it an ideal solution for a wide range of RF and precision
equipment switching needs.
5 kV for RF1 to RF4 and RFC pins
2.5 kV for all other pins
Integrated driver removes the need for an external driver
Supply voltage: 3.0 V to 3.6 V
An integrated driver chip generates a high voltage to
electrostatically actuate switch that can be controlled by a parallel
interface and a serial peripheral interface (SPI). All four switches
are independently controllable.
CMOS/LVTTL compatible
The device is packaged in a 24-lead, 5 mm × 4 mm × 1.45 mm,
lead frame chip-scale package (LFCSP).
Parallel and SPI Interface
Independently controllable switches
Switch is in an open state with no power supply present
Requirement to avoid floating nodes on all RFx pins (see the
Floating Node section)
5 mm × 4 mm × 1.45 mm, 24-lead LFCSP
Operating temperature range: 0°C to +85°C
To ensure optimum operation of the ADGM1004, follow the
Critical Operational Requirements section exactly.
The on resistance (RON) performance of the ADGM1004 is
affected by part to part variation, channel to channel variation,
cycle actuations, settling time post turn on, bias voltage, and
temperature changes.
Note that throughout this data sheet, multifunction pins, such
as IN1/SDI, are referred to either by the entire pin name or by a
single function of the pin, for example, SDI, when only that
function is relevant.

1 RFx is RF1, RF2, RF3, and RF4. INx is IN1, IN2, IN3, and IN4.
2 Maximum RON over time is RON (max) + ∆RON TIME (max) = 2.65 Ω.
3 Maximum RON after 1 billion actuations is RON (max) + ΔRON (max) = 7.9 Ω.
4 Actuating the switch at 85°C and measuring RON at 25°C is the most severe condition for ADGM1004 RON drift over actuations.
5 Failure occurs when 50% of a sample lot fails. For more details, see the Cumulative On Switch Lifetime section.
6 Switch is settled after 75 μs. Do not apply RF power between 0 μs and 75 μs.
7 Disable the internal oscillator to eliminate feedthrough. When the internal oscillator and charge pump circuitry is disabled, the VCP pin (Pin 24) must be driven with
80 V dc (VCPEXT) from an external voltage supply required for MEMS switch actuation, as outlined in Table 3.
8 The spectrum analyzer setup is as follows: RBW = 200 Hz, video bandwidth (VBW) = 2 Hz, span = 100 kHz, input attenuator = 0 dB, the detector type is peak, and the
maximum hold is off. The fundamental feedthrough noise or harmonic (whichever is higher) is tested.
9 For more details, see the Low Power Mode section.
10 For more details, see the Internal Oscillator Feedthrough Mitigation section.

Mnemonic Description
1
IN1/SDI
Parallel Logic Digital Control Input 1. The voltage applied to this pin controls the gate of the RF1 to RFC
MEMS switch. In SPI mode, this pin is the serial data input pin. In parallel mode, if the IN1 pin is low, the
RF1 to RFC switch is open (off). If the IN1 pin is high, the RF1 to RFC switch is closed (on). In SPI mode, this
pin functions as the serial data input (SDI) pin.
2
IN2/CS
Parallel Logic Digital Control Input 2. The voltage applied to this pin controls the gate of the RF2 to RFC
MEMS switch. In parallel mode, if IN2 is low, the RF2 to RFC switch is open (off). If IN2 is high, the RF2 to
RFC switch is closed (on). In SPI mode, this pin is the chip select (CS) pin. CS is an active low signal that
selects the slave device with which the master device intends to communicate. Typically, there is a
dedicated CS signal between the master device and each slave device. The CS pin also functions to
synchronize and frame the communications to and from the slave device.

4
IN3/SCLK
IN4/SDO
GND
Parallel Logic Digital Control Input 3. The voltage applied to this pin controls the gate of the RF3 to RFC
MEMS switch. In parallel mode, if IN3 is low, the RF3 to RFC switch is open (off). If IN3 is high, the RF3 to
RFC switch is closed (on). In SPI mode, this pin functions as the serial clock (SCLK) pin that synchronizes the
slave device(s) to the master device. Typically, the SCLK signal is shared for all slave devices on the serial
bus. The SCLK signal is always driven by the master device.
Parallel Logic Digital Control Input 4. The voltage applied to this pin controls the gate of the RF4 to RFC
MEMS switch. In parallel mode, if IN4 is low, the RF4 to RFC switch is open (off). If IN4 is high, the RF4 to
RFC switch is closed (on). In SPI mode, this pin functions as the serial data output (SDO) pin. Typically, the
SDO pin is shared for all slave devices on the serial bus. The SDO pin is driven by only one slave device at a time,
otherwise it is high impedance. The SDO pin is always high impedance when the CS pin is deasserted high.

PIN/SPI
Parallel or Serial Logic Control Enable Pin. The SPI interface is enabled when this pin is high. When this pin
is low the parallel digital interface is enabled.
7
EXTD_EN
External Voltage Drive Enable. In normal operation, set EXTD_EN low to enable the built in 10 MHz oscillator,
which enables the internal driver IC voltage boost circuitry. Setting EXTD_EN high disables the internal 10 MHz
oscillator and driver boost circuitry. With the oscillator disabled, the switch can still be controlled via the
logic interface pins (IN1 to IN4) or via SPI interface, but the VCP pin must be driven with 80 V dc from an
external voltage supply. In this mode, the ADGM1004 only consumes 50 μA maximum supply current.
Disabling the internal oscillator eliminates the associated 10 MHz noise feedthrough from the switch.

TERMINOLOGY
Insertion Loss
Second-Order Intermodulation Intercept (IP2)
Insertion loss is the amount of signal attenuation between the
input and output ports of the switch when the switch is in the
on state. Expressed in decibels, ensure that insertion loss is as
small as possible for maximum power transfer.
IP2 is the intersection point of the fundamental POUT vs. PIN
extrapolated line and the second-order intermodulation products
extrapolated line of a two-tone test. IP2 is a figure of merit that
characterizes the switch linearity.
An example calculation of insertion loss based on the setup in
Figure 32 is as follows:
Second Distortion Harmonic (HD2)
HD2 is the amplitude of the second distortion harmonic, where, for
a signal whose fundamental frequency is f, the second distortion
harmonic has a frequency of 2 f. This measurement is a single-
tone test expressed with reference to the carrier signal (dBc).
Insertion Loss (dB) = −20log10|SRF2RFC
|
where SRF2RFC is the transmission coefficient measured from RF2
to RFC with RF2 in the on position. All unused switches are in
the off position and terminated in a purely resistive load of 50 Ω.
Third Distortion Harmonic (HD3)
HD3 is the amplitude of the third distortion harmonic, where, for a
signal whose fundamental frequency is f, the third distortion
harmonic has a frequency of 3 f. This measurement is a single
tone test expressed with reference to the carrier signal (dBc).
Isolation
Isolation is the amount of signal attenuation between the input
and output ports of the switch when the switch is in the off
state. Expressed in decibels, ensure that isolation is as large as
possible.
On Switching Time (tON
)
tON is the time it takes for the switch to turn on. tON is measured
An example calculation of isolation based on the setup in Figure 33
is as follows:
from 50% of the control signal (INx) to 90% of the on level. No
power was applied through the switch during this test (cold
switched). The switch was terminated into a 50 Ω load.
Isolation (dB) = −20log10|SRFCRF1
|
where SRFCRF1 is the transmission coefficient measured from RFC
to RF1 with RF1 in the off position. All unused switches are in
the off position and terminated in a purely resistive load of 50 Ω.
Off Switching Time (tOFF
)
tOFF is the time it takes for the switch to turn off. tOFF is measured
from 50% of the control signal (INx) to 10% of the on level. No
power was applied through the switch during this test (cold
switched). The switch was terminated into a 50 Ω load.
Crosstalk
Crosstalk is a measure of unwanted signals coupled through
from one channel to another because of parasitic capacitance.
Actuation Frequency
The actuation frequency refers to the speed at which the
ADGM1004 can be switched on and off. The actuation
frequency is dependent on both the settling times and the on
and off switching times.
An example calculation of crosstalk based on the setup in
Figure 35 is as follows:
Crosstalk (dB) = −20log10|SRF1RF2
|
where SRF1RF2 is the transmission coefficient measured from RF1
to RF2 with RF1 in the off position and RF2 in the on position.
All unused switches are in the off position and terminated in a
purely resistive load of 50 Ω.
Power-Up Time
The power-up time is a measure of the time required for the
device to power up and start to pass 90% of an RF input signal
after the VDD pin reaches 95%.
Return Loss
Video Feedthrough
Return Loss is the magnitude of the reflection coefficient
expressed in decibels, and the amount of reflected signal relative
to the incident signal.
Video feedthrough is a measure of the spurious signals present
at the RFx ports of the switch when the control voltage is switched
from high to low or from low to high without an RF signal present.
An example calculation of return loss based on the setup in
Figure 32 is as follows:
Internal Oscillator Frequency
The internal oscillator frequency is the value of the on-board
oscillator that drives the gate control chip of the ADGM1004.
Return Loss (dB) = −20log10|S11|
where S11 is the reflection coefficient of the port under test.
Internal Oscillator Feedthrough
The internal oscillator feedthrough is the amount of internal
oscillator signal that feeds through to the RFx and RFC pins of
the switch. This signal appears as a noise spur on the RFx and
RFC pins of the switch at the frequency the oscillator is
operating at and the harmonics thereof.
Third-Order Intermodulation Intercept (IP3)
IP3 is the intersection point of the fundamental POUT vs. PIN
extrapolated line and the third-order intermodulation products
extrapolated line of a two-tone test. IP3 is a figure of merit that
characterizes the switch linearity.

THEORY OF OPERATION
The ADGM1004 is a wideband SP4T switch fabricated using
Analog Devices MEMS switch technology. This technology
enables high power, low loss, low distortion GHz switches for
use in demanding RF applications.
When the bias voltage between the gate and the source exceeds
the threshold voltage of the switch (VTH) the contacts on the
beam touch the drain, which completes the circuit between the
source and the drain and turns the switch on. When the bias
voltage is removed, that is, the 0 V on the gate electrode, the
beam acts as a spring generating a sufficient restoring force to
open the connection between the source and the drain, thus
breaking the circuit and turning the switch off.
The MEMS switch simultaneously brings together high
frequency RF performance and 0 Hz/dc precision performance.
This combination, coupled with superior reliability and a tiny
surface-mountable form factor, makes the MEMS switch an
ideal switching solution for all RF and precision signal
instrumentation needs.
The silicon cap covering the switch die is shown in Figure 44. This
cap hermetically seals the switch, which improves reliability.
The switch contacts do not suffer from dry switching or low power
switching lifetime degradation.
Figure 44 shows a cross section of the switch with dimensions.
The switch is an electrostatically actuated cantilever beam
connected in a 3-terminal configuration. Functionally, the switch is
analogous to a field effect transistor (FET). The terminals can
be used as a source, gate, or drain.
PARALLEL DIGITAL INTERFACE
The ADGM1004 is controlled via a parallel digital interface.
Standard complimentary metal-oxide semiconductor (CMOS)/
low voltage transistor to transistor logic (LVTTL) signals
applied through this interface control the actuation or release of
all ADGM1004 switch channels. Gate signals applied are
boosted to provide the required voltages required to actuate the
MEMS switch.

in 4-wire SP4T mode. In parallel mode, Pin 1 to Pin 4 (IN1 to
IN4) control the switching functions of the ADGM1004. When
a Logic 1 is applied to one of these pins, the gate of the
corresponding switch is activated and the switch turns on.
Conversely, when a Logic 0 is applied to one of these pins, the
switch turns off. Note that it is possible to connect more than
one RFx input to RFC at a time. See Table 6 for the ADGM1004
truth table.

When a dc actuation voltage is applied between the gate
electrode and the source (the switch beam), an electrostatic
force is generated, resulting in attracting the beam toward the
substrate. A separate on-board driver IC generates the 80 V bias
voltage used for actuation.

modes of SPI operation are: addressable and daisy-chain.
The target register address of an SPI command is determined on
the eighth SCLK rising edge. Data from this register propagates
out on the SDO pin from the 9th to the 16th SCLK falling edge

edge during SPI writes. During any SPI command, the SDO pin
sends out eight alignment bits on the first eight SCLK falling
edges. The alignment bits observed at the SDO pin are 0x25.

The ADGM1004 can only enter daisy-chain mode from

ADGM1004 receives this command, the SDO pin of the devices
sends out the same command because the alignment bits at the
SDO pin are 0x25. This command allows multiple daisy-
chained devices to enter daisy-chain mode in a single SPI frame.
A hardware reset is required to exit daisy-chain mode.

Hardware Reset
INTERNAL OSCILLATOR FEEDTHROUGH
MITIGATION
The digital section of the ADGM1004 goes through an
initialization phase during VDD power-up. To hardware reset the
device, power cycle the VDD input. After power-up or a hardware
reset, ensure that there is a minimum of 10 μs from the time of
power-up or reset before any SPI command is issued. Ensure that
In normal operation, the 80 V actuation voltage is supplied by
the driver IC. Setting the EXTD_EN pin low enables the built in
10 MHz oscillator. This setting enables the charge pump circuitry
to generate the 80 V required for MEMS switch actuation. The
internal oscillator is a source of noise that couples through to
the RF ports. The magnitude of this feedthrough noise spur is
specified in Table 1 and is typically −123 dBm or −146 dBm/Hz
when one switch is on. To eliminate the internal oscillator
feedthrough, set the EXTD_EN pin high to disable the internal
oscillator and charge pump circuitry. When the internal oscillator
and charge pump circuitry is disabled, the VCP pin must be
driven with 80 V dc (VCPEXT) from an external voltage supply
required for MEMS switch actuation, as shown in Table 5. The
switch can still be controlled via the digital logic interface pins.
V
V
DD does not drop out during the 10 μs initialization phase because
DD dropout can result in incorrect operation of the ADGM1004.
Internal Error Status
When an internal error is detected in the device, the internal
error is flagged by the INTERNAL_ERROR bits (Bits[7:6]) of
the SWITCH_DATA register (Register 0x20), as shown in Table 9.
An internal error results from an error in the configuration of
the device at power up.
INTERNAL OSCILLATOR FEEDTHROUGH
The ADGM1004 has an internal oscillator running at a nominal
10 MHz. This oscillator drives the charge pump circuitry that
provides the actuation voltage for each switch gate electrode.
Although this oscillator is low power, the 10 MHz signal is
coupled to the switch and is considered a noise spur on the
switch channels. The magnitude of this feedthrough noise spur is
specified in Table 1 and is typically −123 dBm or −146 dBm/Hz
when one switch is on. When all four switches are simultaneously
on, the feedthrough goes up to −120 dBm. VDD level and
temperature changes affect the frequency of the noise spur. For
the maximum and minimum frequency range over temperature
and voltage supply range, see Table 1.
LOW POWER MODE
Setting the EXTD_EN pin high shuts down the internal
oscillator. The ADGM1004 enters a low power quiescent state,
drawing only 50 μA maximum supply current.

the EXTD_EN pin high and apply 80 V dc directly to the VCP pin
to disable the internal oscillator and eliminate all oscillator
feedthrough. The switches can then be controlled normally via
the logic control interface, IN1 to IN4.
TYPICAL OPERATING CIRCUIT
Figure 49 shows the typical operating circuit for the ADGM1004
as used in the EVAL-ADGM1004SDZ evaluation board. A 47 pF
(100 V rated) external capacitor (CCP) is required on the VCP pin.
This capacitor is a holding capacitor for the 80 V dc gate drive
voltage.
To avoid any floating nodes, connect a 10 MΩ shunt resistor to
GND on all RFx pins (RF1 to RF4, and RFC), as shown in
Figure 49. See the Floating Node section for more information.
In the circuit shown in Figure 49, VDD is connected to 3.3 V. EP1
connects to EP2 internally. Typically, one large GND pad on the
PCB is used to short together EP1 and EP2. Figure 49 shows the

APPLICATIONS INFORMATION
SWITCHABLE RF ATTENUATOR
RECONFIGURABLE RF FILTER
RF attenuator networks are commonly used in RF instrumentation
equipment, such as vector network analyzers, spectrum analyzers,
and signal generators. Routing RF signals through an attenuator
can enable the equipment to accept higher power signals and,
therefore, increase the dynamic range of the instrument. In
RF attenuation applications like the vector network analyzers,
spectrum analyzers, and signal generators, maintaining the
bandwidth of the signal after the signal passes through the
network is critical. Any degradation of the signal reduces the
performance of the equipment. Therefore, the RF characteristics
of the switches used for routing are an integral part of the quality
of an attenuator network.
A reconfigurable RF filter is advantageous in many RF front-
end applications. A reconfigurable RF filter provides more saved
space. As space becomes more constrained in applications, the
option to have an economical reconfigurable RF filter instead of
individual frequency dependent filters is preferred.
The ADGM1004 low flat insertion loss, wide RF bandwidth,
low parasitic, low capacitance, and high linearity are required to
turn on the lump components (capacitor and inductor), which
make the MEMS switch suited for reconfigurable filter application.
In applications such as wireless communications or mobile radios,
the number of bands and/or modes constantly increases. A
reconfigurable RF filter allows more bands and/or modes to be
covered using the same components.
The ADGM1004 MEMS switch with low flat insertion loss, wide
RF bandwidth, and high reliability is suited for use as a switchable
RF attenuator. The ADGM1004, as an SP4T switch, also brings
added flexibility. Figure 50 shows an example attenuation
network configuration using two ADGM1004 switches and
three different attenuators. The fourth channel of the switches is
used as a nonattenuated route in Figure 50.
Figure 51 shows an example of a reconfigurable band-pass filter.
The topology shown is of a generalized, two section, inductively
coupled, single-ended band-pass filter, nominally centered on a
400 MHz ultrahigh frequency (UHF) band. The MEMS switches
are positioned in series with each shunt inductor.
The function of the switches includes or omits a shunt inductor
from the circuit. Changing the shunt inductor value affects the
bandwidth and center frequency of the filter. Using inductance
values from 15 nH to 30 nH significantly alters the bandwidth
and center frequency, allowing the filter to dynamically configure
to operate in the UHF bands or very high frequency (VHF)
bands while preserving the 50 Ω match on the input and output
ports. The low RON value and wide bandwidth of the MEMS
switch makes the switch an ideal choice for this application. The
low RON reduces the negative effect a series resistance has on the
quality factor of the shunt inductor. The large bandwidth enables
higher frequency band-pass filters.

CRITICAL OPERATIONAL REQUIREMENTS
SYSTEM ERROR CONSIDERATIONS DUE TO
ON-RESISTANCE DRIFT
FLOATING NODE
The ADGM1004 has no internal impedance to ground, and
charges can develop on the switch terminals leading to unreliable
switch behavior To mitigate this behavior, provide a discharge
path to all switch nodes. Figure 53 to Figure 56 show examples
of cases to avoid where floating nodes can occur when using the
switch. Conditions to avoid include the following:
The RON performance of the ADGM1004 is affected by part to
part variation, channel to channel variation, cycle actuations,
settling time post turn on, bias voltage, and temperature changes
(see Figure 6 to Figure 13).
In a 50 Ω system, the on-resistance drift over switch actuations
(ΔRON) can introduce system inaccuracy. Figure 52 shows the
ADGM1004 connected with the load in a 50 Ω system, where
RS is the source impedance. TO calculate the system error
caused by the ADGM1004 on-resistance drift, use the following
equation:
Leaving the RFx pins open circuit (see Figure 53).
Connecting a series capacitor directly to the switch (see
Figure 54).

Provide a discharge path to the switch nodes to avoid floating
nodes. In a typical application, a 50 Ω termination connected to
the switch provides this path. Driving switch nodes with a
device of adequate impedance (<10 MΩ) provides a discharge
path. If there is no discharge path in the application circuit, add
a 10 MΩ shunt resistor or inductor on the source RFx pin of the
MEMS switch to provide the discharge path. Note that the
shunt resistors introduce leakage. Figure 57 shows an example
of a configuration providing a discharge path.

Leaving the switch in an on state for a long period affects the
lifetime of the switch because of mechanical degradation effects.
These effects can result in the switch failing to turn off. Figure 60
shows a failure rate at 50°C where the mean time to failure is
7.2 years (2628 days), resulting in 50% of the sample lot failing
at this point.
Figure 61. Avoid Having a Large Capacitor Directly Connected to the
MEMS Switch
Temperatures above 50°C further reduce the switch lifetime.
The cumulative on switch lifetime specification is also duty cycle
dependent. If the user operates the MEMS switch with a duty
cycle of less than 50% the lifetime of the MEMS switch improves.
