GENERAL DESCRIPTION
The ADL5365 provides two switched LO paths that can be
used in TDD applications where it is desirable to rapidly switch
between two local oscillators. LO current can be externally set
using a resistor to minimize dc current commensurate with the
desired level of performance. For low voltage applications, the
ADL5365 is capable of operation at voltages down to 3.3 V with
substantially reduced current. Under low voltage operation, an
additional logic pin is provided to power down (<200 μA) the
circuit when desired.
The ADL5365 uses a highly linear, doubly balanced passive
mixer core along with integrated RF and LO balancing circuitry
to allow for single-ended operation. The ADL5365 incorporates
an RF balun, allowing for optimal performance over a 1200 MHz
to 2500 MHz RF input frequency range using high-side LO
injection for RF frequencies from 1700 MHz to 2500 MHz and
low-side injection for frequencies from 1200 MHz to 1700 MHz.
The balanced passive mixer arrangement provides good LO-to-
RF leakage, typically better than −30 dBm, and excellent inter-
modulation performance. The balanced mixer core also provides
extremely high input linearity, allowing the device to be used in
demanding cellular applications where in-band blocking signals
may otherwise result in the degradation of dynamic performance.
The ADL5365 is fabricated using a BiCMOS high performance
IC process. The device is available in a 5 mm × 5 mm, 20-lead
LFCSP and operates over a −40°C to +85°C temperature range.
An evaluation board is also available.

ADL5365
CIRCUIT DESCRIPTION
The ADL5365 consists of two primary components: the radio
frequency (RF) subsystem and the local oscillator (LO) subsystem.
The combination of design, process, and packaging technology
allows the functions of these subsystems to be integrated
into a single die, using mature packaging and interconnection
technologies to provide a high performance, low cost design
with excellent electrical, mechanical, and thermal properties.
In addition, the need for external components is minimized,
optimizing cost and size.
The resulting balanced RF signal is applied to a passive mixer
that commutates the RF input with the output of the LO subsystem.
The passive mixer is essentially a balanced, low loss switch that
adds minimum noise to the frequency translation. The only
noise contribution from the mixer is due to the resistive loss
of the switches, which is in the order of a few ohms.
As the mixer is inherently broadband and bidirectional, it
is necessary to properly terminate all the idler (M × N product)
frequencies generated by the mixing process. Terminating the
mixer avoids the generation of unwanted intermodulation
products and reduces the level of unwanted signals at the IF
output. This termination is accomplished by the addition of a
sum network between the IF output and the mixer.
The RF subsystem consists of an integrated, low loss RF balun,
passive MOSFET mixer, and a sum termination network.
The LO subsystem consists of an SPDT-terminated FET switch
and a three-stage limiting LO amplifier. The purpose of the LO
subsystem is to provide a large, fixed amplitude, balanced signal
to drive the mixer independent of the level of the LO input.
The IP3 performance can be optimized by adjusting the supply
current with an external resistor. Figure 37 and Figure 39
illustrate how various bias resistors affect the performance with a
5 V supply. Additionally, dc current can be saved by increasing
the resistor. It is permissible to reduce the dc supply voltage to
as low as 3.3 V, further reducing the dissipated power of the
part. (Note that no performance enhancement is obtained by
reducing the value of these resistors and excessive dc power
dissipation may result.)
A block diagram of the device is shown in Figure 49.

The LO amplifier is designed to provide a large signal level to
the mixer to obtain optimum intermodulation performance.
The resulting amplifier provides extremely high performance
centered on an operating frequency of 1700 MHz. The best
operation is achieved with either high-side LO injection for RF
signals in the 1200 MHz to 1700 MHz range or low-side injection
for RF signals in the 1700 MHz to 2500 MHz range. Operation
outside these ranges is permissible, and conversion gain is
extremely wideband, easily spanning 1200 MHz to 2500 MHz,
but intermodulation is optimal over the aforementioned ranges.

The ADL5365 has two LO inputs permitting multiple synthesizers
to be rapidly switched with extremely short switching times
(<40 ns) for frequency agile applications. The two inputs are
applied to a high isolation SPDT switch that provides a constant
input impedance, regardless of whether the port is selected, to
avoid pulling the LO sources. This multiple section switch also
ensures high isolation to the off input, minimizing any leakage
from the unwanted LO input that may result in undesired IF
responses.

Figure 49. Simplified Schematic
RF SUBSYSTEM
The single-ended, 50 Ω RF input is internally transformed to a
balanced signal using a low loss (<1 dB) unbalanced-to-balanced
(balun) transformer. This transformer is made possible by an
extremely low loss metal stack, which provides both excellent
balance and dc isolation for the RF port. Although the port can
be dc connected, it is recommended that a blocking capacitor be
used to avoid running excessive dc current through the part.
The RF balun can easily support an RF input frequency range
of 1200 MHz to 2500 MHz.
The single-ended LO input is converted to a fixed amplitude
differential signal using a multistage, limiting LO amplifier.
This results in consistent performance over a range of LO input
power. Optimum performance is achieved from −6 dBm to
+10 dBm, but the circuit continues to function at considerably
lower levels of LO input power.

ADL5365
The performance of this amplifier is critical in achieving a
high intercept passive mixer without degrading the noise floor
of the system. This is a critical requirement in an interferer rich
environment, such as cellular infrastructure, where blocking
interferers can limit mixer performance. The bandwidth of the
intermodulation performance is somewhat influenced by the
current in the LO amplifier chain. For dc current sensitive
applications, it is permissible to reduce the current in the
LO amplifier by raising the value of the external bias control
resistor. For dc current critical applications, the LO chain
can operate with a supply voltage as low as 3.3 V, resulting in
substantial dc power savings.
In addition, when operating with supply voltages below 3.6 V,
the ADL5365 has a power-down mode that permits the dc
current to drop to <200 μA.
All of the logic inputs are designed to work with any logic family
that provides a Logic 0 input level of less than 0.4 V and a Logic 1
input level that exceeds 1.4 V. All logic inputs are high impedance
up to Logic 1 levels of 3.3 V. At levels exceeding 3.3 V, protection
circuitry permits operation up to 5.5 V, although a small bias
current is drawn.

APPLICATIONS INFORMATION
BASIC CONNECTIONS
BIAS RESISTOR SELECTION
An external resistor, RBIAS LO, is used to adjust the bias current
of the integrated amplifiers at the LO terminals. It is necessary
to have a sufficient amount of current to bias the internal LO
amplifier to optimize dc current vs. optimum IIP3 performance.
Figure 37 and Figure 39 provide the reference for the bias resistor
selection when lower power consumption is considered at the
expense of conversion gain and IP3 performance.
The ADL5365 mixer is designed to up- or downconvert
between radio frequencies (RF) from 1200 MHz to 2500 MHz and
intermediate frequencies (IF) from dc to 450 MHz. Figure 50
depicts the basic connections of the mixer. It is recommended to
ac-couple RF and LO input ports to prevent non-zero dc voltages
from damaging the RF balun or LO input circuit. The RFIN
capacitor value of 3 pF is recommended to provide the optimized
RF input return loss for the desired frequency band.
MIXER VGS CONTROL DAC
For upconversion, the IF input, Pin 18 (IFON) and Pin 19
(IFOP), must be driven differentially or by using a 1:1 ratio
transformer for single-ended operation. A 3 pF capacitor is
recommended for the RF output, Pin 2 (RFIN).
The ADL5365 features two logic control pins, Pin 12 (VGS0)
and Pin 13 (VGS1), that allow programmability for internal
gate-to-source voltages for optimizing mixer performance over
desired frequency bands. The evaluation board defaults both
VGS0 and VGS1 to ground. Power conversion loss, NF, and
IIP3 can be optimized, as shown in Figure 35 and Figure 36.
IF PORT
The real part of the output impedance is approximately 50 Ω, as
seen in Figure 26, which matches many commonly used SAW
filters without the need for a transformer. This results in a voltage
conversion loss that is approximately the same as the power
conversion loss, as shown in Table 3.

Description
Default Conditions
C2, C6, C8,
C20, C21
Power Supply Decoupling. Nominal supply decoupling consists of
a 10 μF capacitor to ground in parallel with a 10 pF capacitor to
ground positioned as close to the device as possible.
C2 = 10 μF (Size 0603),
C6, C8, C20, C21 = 10 pF (Size 0402)
C1, C4, C5
RF Input Interface. The input channels are ac-coupled through C1.
C4 and C5 provide bypassing for the center taps of the RF input baluns.
C1 = 3 pF (Size 0402), C4 = 10 pF (Size 0402),
C5 = 0.01 μF (Size 0402)
T1, R1, C24, C25 IF Output Interface. T1 is a 1:1 impedance transformer used to provide
a single-ended IF output interface. Remove R1 for balanced output
T1 = TC1-1-13M+ (Mini-Circuits),
R1 = 0 Ω (Size 0402),
operation. C24 and C25 are used to block the dc bias at the IF ports.
C24, C25 = 560 pF (Size 0402)
C10, C12, R4
LO Interface. C10 and C12 provide ac coupling for the LO1_IN and
LO2_IN local oscillator inputs. LOSEL selects the appropriate LO input
for both mixer cores. R4 provides a pull-down to ensure that LO1_IN is
enabled when the LOSEL test point is logic low. LO2_IN is enabled
when LOSEL is pulled to logic high.
C10, C12 = 22 pF (Size 0402),
R4 = 10 kΩ (Size 0402)
R21
PWDN Interface. R21 pulls the PWDN logic low and enables the device.
The PWR_UP test point allows the PWDN interface to be exercised
using the an external logic generator. Grounding the PWDN pin for
nominal operation is allowed. Using the PWDN pin when supply
voltages exceed 3.3 V is not allowed.
R21 = 10 kΩ (Size 0402)
C22, L3, R9, R14,
R22, R23, VGS0,
VGS1
Bias Control. R22 and R23 form a voltage divider to provide 3 V for
logic control, bypassed to ground through C22. VGS0 and VGS1
jumpers provide programmability at the VGS0 and VGS1 pins. It is
recommended to pull these two pins to ground for nominal operation.
R9 sets the bias point for the internal LO buffers. R14 sets the bias point
for the internal IF amplifier.
C22 = 1 nF (Size 0402), L3 = 0 Ω (Size 0603),
R9 = 1.1 kΩ (Size 0402), R14 = 0 Ω (Size 0402),
R22 = 10 kΩ (Size 0402), R23 = 15 kΩ (Size 0402),
VGS0 = VGS1 = 3-pin shunt
