Description
The SKY73025 is a fully integrated diversity mixer that includes
Local Oscillator (LO) drivers, an LO switch, high linearity mixers,
and large dynamic range Intermediate Frequency (IF) amplifiers.
Low loss RF baluns have also been included to reduce design
complications and lower system cost.
The SKY73025 features an input IP3 of +23.5 dBm and a Noise
Figure (NF) of 9.8 dB, making the device an ideal solution for high
dynamic range systems such as 2G/3G base station receivers.
The LO switch provides more than 45 dB of isolation between LO
inputs and supports the switching time required for GSM/EDGE
base stations.
The SKY73025 is manufactured using a robust silicon BiCMOS
process and has been designed for optimum long-term reliability.
The SKY73025 diversity downconversion mixer is provided in a
compact, 36-pin 6 x 6 mm Multi-Chip Module (MCM). A functional
block diagram is shown in Figure 1. The pin configuration and
package are shown in Figure 2. Signal pin assignments and
functional pin descriptions are provided in Table 1.

Package Dimensions
The PCB footprint for the SKY73025 is provided in Figure 7.
Figure 8 shows the package dimensions for the 36-pin MCM, and
Figure 9 provides the tape and reel dimensions.
Package and Handling Information
Since the device package is sensitive to moisture absorption, it is
baked and vacuum packed 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.
THE SKY73025 is rated to Moisture Sensitivity Level 3 (MSL3) at
260 °C. It can be used for lead or lead-free soldering. For
additional information, refer to the Skyworks Application Note,
PCB Design & SMT Assembly/Rework Guidelines for MCM-L
Packages, document number 101752.
Care must be taken when attaching this product, whether it is
done manually or in a production solder reflow environment.
Production quantities of this product are shipped in a standard
tape and reel format. For packaging details, refer to the Skyworks
Application Note, Tape and Reel, document number 101568.
Electrostatic Discharge (ESD) Sensitivity
The SKY73025 is a static-sensitive electronic device. Do not
operate or store near strong electrostatic fields. Take proper ESD
precautions.
