Description
The SKY13522-644LF is a single-pole, double-throw (SPDT)
switch used for single-ended switching in cellular applications.
Using advanced switching technologies, the SKY13522-644LF
maintains low insertion loss and high isolation for all switching
paths.
Depending on the logic voltage level applied to the control pin
(V1), the antenna port (RFC) is connected to one of two switched
RF outputs (RF1 or RF2) through a low insertion loss path, while
the path between the antenna port and the other RF port is in a
high isolation state.
The SKY13522-644LF is provided in a small 8-pin, 1.1 x 1.1 mm
Quad Flat No-Lead (QFN) package.
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.

Evaluation Board Description
The SKY13522-644LF Evaluation Board is used to test the
performance of the SKY13522-644LF SPDT Switch. An Evaluation
Board schematic diagram is provided in Figure 7. An assembly
drawing for the Evaluation Board is shown in Figure 8.
Package Dimensions
The PCB layout footprint for the SKY13522-644LF is shown in
Figure 9. Typical part markings are shown in Figure 10. Package
dimensions for the 8-pin QFN are shown in Figure 11, and tape
and reel dimensions are provided in Figure 12.
Package and Handling Information
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 SKY13522-644LF is rated to Moisture Sensitivity Level 1
(MSL1) at 260 °C. It can be used for lead or lead-free soldering.
For additional information, refer to the Skyworks Application Note,
Wafer Level Chip Scale Packages: SMT Process Guidelines and
Handling Considerations, document number 201676.
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.
