CX42053
700 – 1000 MHz High Dynamic Range, Diversity Receiver Front End
Skyworks’ CX42053 is an integrated, high-dynamic range, low-noise receiver down
converter for two-channel diversity systems. It includes a Low Noise Amplifier
(LNA) followed by a double-balanced active mixer. The CX42053 has dual Local
Oscillator (LO) inputs, selected using an external switch interface. The internal
attenuator is integrated with the LNA. The attenuator function is also controlled
using an externally controlled CMOS-compatible interface.
Figure 1 shows a functional block diagram for the CX42053. The 24-pin Plastic
Quad Flat Pack (PQFP) device package and pinout are shown in Figure 2.

CX42053
Diversity Receiver Front End
Technical Description
The CX42053 consists of two identical channels, A and B, that
were specifically designed for the purpose of diversity in base
station applications.
Each channel consists of a single-ended LNA and a doublebalanced differential mixer. The LNAs share a common CMOScompatible attenuator control switch, which bypasses the LNA,
providing 20 dB of attenuation.
Each channel shares two independent LO signals, LO1 and
LO2, that are selected using a common CMOS-compatible
control signal. With this ability, the device can be used in
applications where frequency hopping is required.
The LNAs and mixers are independently biased. This allows
design flexibility with power management functions in base
station receivers.
Electrical and Mechanical Specifications
The signal pin assignments and functions are described in
Table 1. The absolute maximum ratings of the CX42053 are
provided in Table 2. The recommended operating conditions are
specified in Table 3 and electrical specifications are provided in
Table 4. Table 5 provides additional electrical specifications for
full channel performance.
Typical performance characteristics of the CX42053 are
illustrated in Figures 3 through 9.

CX42053
Evaluation Board Description
LNA Testing Procedure_______________________________
The CX42053 Evaluation Board is used to test the CX42053
mixer and LNA performance. The CX42053 Evaluation Board
schematic diagram is shown in Figure 10. Table 6 contains I/O
matching network components used in the schematic. The
schematic shows the basic design of the Evaluation Board for
the RF range of 800 to 1000 MHz. The IF matching circuitry has
been optimized for 60 to 130 MHz. Figure 11 displays the
Evaluation Board layout.
Use the following procedure to set up the CX42053 Evaluation
Board for LNA testing. Refer to Figure 12 for guidance:
1.
Set all the DIP switches to OFF. For information on the
switch settings, refer to Table 7.
2.
Connect the CX42053 Evaluation Board to ±5 VDC power
supplies using insulated supply cables. VDD should be set
to +5.0 V and VSS to –5.0 V. If available, enable the
current limiting function of the power supplies as follows:
Circuit Design Configurations ________________________
+ 5 VDC supply current limit = 200 mA
–5 VDC supply current limit = 50 mA
The following design considerations are general in nature and
must be followed regardless of final use or configuration:
1.
Paths to ground should be made as short as possible.
2.
The downset paddle of the PQFP provides necessary
electrical grounding and is the main thermal conduit for
heat dissipation. Any printed circuit board using the
CX42053 must have sufficient solder mask clearance
beneath the IC (i.e., approximately 110 percent of the
downset paddle). This provides adequate solder coverage
for the downset paddle and minimizes excessive lead
standoff. Multiple vias to the grounding layer beneath the
device are required for maximum thermal relief.
3.
4.
5.
Connect red and yellow banana plugs to VDD, a purple
plug to VSS, and a black plug to ground. Connect a threeslot plug to the side (JP1) and a two-slot plug to the top
(JP2).
The inclusion of external bypass capacitors on the VSS
and VDD voltage inputs of the LNAs and mixers is
recommended. The application schematic in Figure 10
shows these capacitors (1000 pF and 12 pF) in shunt with
each control switch, as well as the VSS supply. The
1000 pF capacitor serves as a low frequency bypass, while
the 12 pF capacitor prevents any RF signals from coupling
on to the DC supply voltages. It is recommended that the
bypass capacitors be placed as close as possible to the
CX42053 for best results.
The LNA receives its bias voltage via the LNA output pin.
The use of a blocking capacitor (RF short) on the LNA
input/output and mixer input is required.
Ceramic or wire-wound balanced transformers (baluns)
may be used to provide the differential input to the active
mixer. The secondary center tap of these baluns provides
the DC return path for the mixer bias current. Balun
selection criterion should include DC current handling
capability, differential phase/amplitude balance, insertion
loss, and temperature performance.
6.
The application of an image-reject filter between the LNA
and mixer is recommended.
7.
For proper switching of the control interface circuits, the
following conditions must be met:
OFF: 0 VDC ≤ VIN ≤ 0.5 VDC @ 30 µA
ON: 3.0 VDC ≤ VIN ≤ VDD @ 120 µA
101431B
March 12, 2002
3.
Connect a signal generator to the LNA A input port (J1).
Set the generator to the desired RF frequency at a power
level of –20 dBm, but do not enable.
4.
Connect a spectrum analyzer to the output port of LNA A
(J2).
5.
Enable the power supply by turning switches #2 and #4
ON.
6.
Enable the RF signal and take measurements.
7.
Repeat steps 3 through 6 for LNA B, but use switches #4
and #5 to enable the power supply.
Mixer Testing Procedure______________________________
Use the following procedure to set up the CX42053 Evaluation
Board for mixer testing. Refer to Figure 13 for guidance:
1.
Set all the DIP switches to OFF. For information on the
switch settings, refer to Table 7.
2.
Connect the CX42053 Evaluation Board to ±5 VDC power
supplies using insulated supply cables. VDD should be set
to +5.0 V and VSS to –5.0 V. If available, enable the
current limiting function of the power supplies as follows:
+ 5 VDC supply current limit = 200 mA
–5 VDC supply current limit = 50 mA
Connect red and yellow banana plugs to VDD, a purple
plug to VSS, and a black plug to ground. Connect a threeslot plug to the side (JP1) and a two-slot plug to the top
(JP2).
3.
Connect a signal generator to the LO1 input port (J9). Set
the generator to the desired LO frequency at a power level
of 0 dBm, but do not enable.

4.
Connect a signal generator to the Mixer A input port (J3).
Set the generator to the desired RF frequency at a power
level of 0 dBm, but do not enable.
after the container seal is broken must be followed. Otherwise,
problems related to moisture absorption may occur when the
part is subjected to high temperature during solder assembly.
5.
Connect a spectrum analyzer to the output port of Mixer A
(J4).
6.
Enable the power supply by turning switches #1 and #4
ON.
7.
Enable LO1 by turning switch #6 ON.
If the part is attached in a reflow oven, the temperature ramp
rate should not exceed 10 °C per second. Maximum
temperature should not exceed 225 °C and the time spent at a
temperature that exceeds 210 °C should be limited to less than
10 seconds. If the part is manually attached, precaution should
be taken to ensure that the part is not subjected to a
temperature that exceeds 300 °C for more than 10 seconds.
8.
Enable the LO signal, then enable the RF signal and take
measurements.
9.
Repeat steps 4 through 8 for mixer B, but use switches #3
and #4 to enable the power supply. If LO2 is desired, turn
switch #6 OFF and connect the LO signal generator to the
LO2 input port (J10).
Care must be taken when attaching this product, whether it is
done manually or in a production solder reflow environment. For
additional details on both attachment techniques, precautions,
and recommended handling procedures, refer to the Skyworks’
document Solder Reflow Application Note, document number
101536.
Caution: If any of the input signals exceed the rated maximum
values, the CX42053 Evaluation Board can be
permanently damaged.
Package Dimensions
Production quantities of this product are shipped in a standard
tape and reel format. For packaging details, refer to the
Skyworks’ document Tape and Reel Information Application
Note, document number 101568.
Electro-Static Discharge (ESD) Sensitivity
Figure 14 shows the package dimensions for the 24-pin
CX42053 PQFP and Figure 15 provides the tape and reel
dimensions.
The CX42053 is a static-sensitive electronic device. Do not
operate or store near strong electrostatic fields. Take proper
ESD precautions.
Package and Handling Information
Since the device package is sensitive to moisture absorption, it
is baked and vacuum packed before shipping. Instructions on
