4. Connect a signal generator to the Mxer A input port (J3).
Set the generator to the desired RF frequency at a power
level of 0 dBm but do not enable.
5. Connect a spectrumanalyzer to the output port of Mxer A
(J4).
6. Enable the power supply by turning switches #1 and #4
ON.
7. Enable LO1 by turning switch #6 ON.
8. Enable the LO signal, then enable the RF signal and take
measurements.
9. Repeat steps 4 through 8 for mxer 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).
Caution:
If any of the input signals exceed the rated maximum
values, the CX42053 Evaluation Board can be
permanently damaged.
Package Dimensions
Figure 14 shows the package dimensions for the 24-pin
CX42053 PQFP and Figure 15 provides the tape and reel
dimensions.
Package and Handling Information
Since the device package is sensitive to moisture absorption, it
is baked and vacuumpacked before shipping. Instructions on
the shipping container label regarding exposure to moisture
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.
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 limted 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.
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.
Production quantities of this product are shipped in a standard
tape and reel format. For packaging details, refer to the
Skyworks’ document

, document number 101568.
Electro-Static Discharge (ESD) Sensitivity
The CX42053 is a static-sensitive electronic device. Do not
operate or store near strong electrostatic fields. Take proper
ESD precautions.
