transformation may cause the internal RF voltages (VP, VM) to exceed Peak

operation above about +20 dBm (100 mW), the complete RF circuit must
be simulated using actual input power and load conditions, and internal
node voltages (VP, VM in Figure 18) monitored to not exceed 30 Vpk.

Operation at Frequencies Below 100 MHz
The PE64904 may be operated below the
100 MHz specified minimum operating frequency.
The total capacitance and peak operating RF
voltage are de-rated down to 1 MHz. Figure 13
shows the total shunt capacitance from 1 MHz
through 100 MHz. As seen in Figure 14, the
maximum RF voltage that can be placed across
the RF terminals or across either RF terminal to
Ground is de-rated as a function of frequency.
Note: Table 1 performance specifications are not guaranteed below 100 MHz.
Figures 13, 14, and 15 reflect performance of a typical PE64904.

PE64904
Product Specification
Serial Interface Operation and Sharing
More than 1 DTC can be controlled by one interface by
utilizing a dedicated enable (SEN) line for each DTC.
SDA, SCL, and VDD lines may be shared as shown in
Figure 17. Dedicated SEN lines act as a chip select such
that each DTC will only respond to serial transactions
intended for them. This makes each DTC change states
sequentially as they are programmed.
The PE64904 is controlled by a three wire SPI-
compatible interface. As shown in Figure 16, the serial
master initiates the start of a telegram by driving the
SEN (Serial Enable) line high. Each bit of the 8-bit
telegram is clocked in on the rising edge of the SCL
(Serial Clock) line. SDA bits are clocked by most
significant bit (MSB) first, as shown in Table 5 and
Figure 16. Transactions on SDA (Serial Data) are
allowed on the falling edge of SCL. The DTC activates
the data on the falling edge of SEN. The DTC does not
count how many bits are clocked and only maintains
the last 8 bits it received.
Alternatively, a dedicated SDA line with common SEN
can be used. This allows all DTCs to change states
simultaneously, but requires all DTCs to be programmed
even if the state is not changed.

The DTC Equivalent Circuit Model includes all
parasitic elements and is accurate in both Series
and Shunt configurations, reflecting physical circuit
behavior accurately and providing very close
correlation to measured data. It can easily be used
in circuit simulation programs. Most parameters are
state independent, and simple equations are
provided for the state dependent parameters.
The Tuning Core capacitance CS represents
capacitance between RF+ and RF- ports. It is
linearly proportional to state (0 to 31 in decimal) in
a discrete fashion. The Series Tuning Ratio is

CP represents the circuit and package parasitics

total capacitance of the DTC is higher due to
parallel combination of CP and CS. In Series
configuration, CS and CP do not add in parallel and
the DTC appears as an impedance transformation
network.

Parasitic inductance due to circuit and package is
modeled as LS and causes the apparent
capacitance of the DTC to increase with frequency
until it reaches Self Resonant Frequency (SRF).
The value of SRF depends on state and is
approximately inversely proportional to the square
root of capacitance.

The overall dissipative losses of the DTC are
modeled by RS, RP1 and RP2 resistors. The
parameter RS represents the Equivalent Series
Resistance (ESR) of the tuning core and is
dependent on state. RP1 and RP2 represent losses
due to the parasitic and biasing networks, and are
state-independent.

Product Specification
Evaluation Board
Layout Recommendations
The 101-0597 Evaluation Board (EVB) was designed
for accurate measurement of the DTC impedance
and loss. Two configurations are available: 1 Port
Shunt (J3) and 2 Port Series (J4, J5). Three
calibration standards are provided. The open (J2)
and short (J1) standards (104 ps delay) are used for
performing port extensions and accounting for
electrical length and transmission line loss. The Thru
(J9, J10) standard can be used to estimate PCB
transmission line losses for scalar de-embedding of
the 2 Port Series configuration (J4, J5).
For optimal results, place a ground fill directly under
the DTC package on the PCB. Layout isolation is
desired between all control and RF lines. When
using the DTC in a shunt configuration, it is
important to make sure the RF-pin is solidly
grounded to a filled ground plane. Ground traces
should be as short as possible to minimize
inductance. A continuous ground plane is preferred
on the top layer of the PCB. When multiple DTCs
are used together, the physical distance between
them should be minimized and the connection
should be as wide as possible to minimize series
parasitic inductance.
The board consists of a 4 layer stack with 2 outer
layers made of Rogers 4350B (εr = 3.48) and 2 inner
layers of FR4 (εr = 4.80). The total thickness of this
board is 62 mils (1.57 mm). The inner layers provide
a ground plane for the transmission lines. Each
transmission line is designed using a coplanar
waveguide with ground plane (CPWG) model using
a trace width of 32 mils (0.813 mm), gap of 15 mils
(0.381 mm), and a metal thickness of 1.4 mils
(0.051 mm).
