2300 MHz to 2900 MHz Balanced Mixer,
LO Buffer and RF Balun
ADL5363
FEATURES
APPLICATIONS
Cellular base station receivers
Transmit observation receivers
Radio link downconverters
GENERAL DESCRIPTION
The ADL5363 uses a highly linear, doubly balanced passive
mixer core along with integrated RF and local oscillator (LO)
balancing circuitry to allow for single-ended operation. The
ADL5363 incorporates an RF balun to provide optimal
performance over a 2300 MHz to 2900 MHz input frequency
range. The balanced passive mixer arrangement provides good
LO-to-RF leakage, typically better than −30 dBm, and excellent
intermodulation 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 might otherwise result in the degradation of
dynamic performance.

Figure 1.
The ADL5363 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 ADL5363 is
capable of operation at voltages down to 3.3 V with substantially
reduced current. For low voltage operation, an additional logic
pin is provided to power down (<200 μA) the circuit when desired.
The ADL5363 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.

ADL5363
CIRCUIT DESCRIPTION
The ADL5363 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.
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 2300 MHz to 2900 MHz.
The RF subsystem consists of an integrated, low loss RF balun,
passive MOSFET mixer, 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.
A block diagram of the device is shown in Figure 48.

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 IP3 performance can be optimized by adjusting the supply
current with an external resistor. Figure 37 and 38 illustrate how
the bias resistor affects the performance with a 5 V supply.
Additionally, dc current can be saved by increasing either or
both resistors. 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.)

BIAS
GENERATOR
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.

ADL5363
LO SUBSYSTEM
The ADL5363 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.
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.
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 ADL5363 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.
All pins, including the RF pins, are ESD protected and have
been tested up to a level of 1500 V HBM and 1250 V CDM.

APPLICATIONS INFORMATION
BASIC CONNECTIONS
BIAS RESISTOR SELECTION
The ADL5363 mixer is designed to downconvert radio frequencies (RF) primarily between 2300 MHz and 2900 MHz to lower
intermediate frequencies (IF) between 30 MHz and 450 MHz.
Figure 49 depicts the basic connections of the mixer. To prevent
nonzero dc voltages from damaging the RF balun or LO input
circuit, ac-couple the RF and LO input ports. The RFIN
matching network consists of a series 1.5 pF capacitor and a
shunt 12 nH inductor to provide the optimized RF input return
loss for the desired frequency band.
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 38 provide the reference for the bias
resistor selection when lower power consumption is considered
at the expense of conversion gain and IP3 performance.
MIXER VGS CONTROL DAC
The ADL5363 features two logic control pins, VGS0 (Pin 12) and
VGS1 (Pin 13), that allow programmability for internal gate-tosource voltages for optimizing mixer performance over desired
frequency bands. The evaluation board defaults both VGS0 and
VGS1 to ground.
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
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.
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.
IF Output Interface. T1 is a 1:1 impedance transformer used
to provide a single-ended IF output interface. Remove R1
for balanced output operation. C24 and C25 are used to
block the dc bias at the IF ports.
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.
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.
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.
