Description
The SKY13524-639LF is a single-pole, four-throw (SP4T) switch
used for single-ended filter switching in cellular applications. The
SKY13524-639LF maintains low insertion loss and high isolation
for all switching paths.
Depending on the logic voltage level applied to the control pins
(V1 and V2), the RFC pin is connected to one of four switched RF
outputs (RF1 to RF4) using a low insertion loss path, while the
paths between the RFC pin and the other RF pins are in a high
isolation state.
The SKY13524-639LF is manufactured in a compact, 14-pin
1.6 x 1.6 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 SKY13524-639LF Evaluation Board is used to test the
performance of the SKY13524-639LF SP4T Switch. An Evaluation
Board schematic diagram is provided in Figure 3. An assembly
drawing for the Evaluation Board is shown in Figure 4.
Package Dimensions
The PCB layout footprint for the SKY13524-639LF is provided in
Figure 5. Typical case markings are shown in Figure 6. Package
dimensions for the 14-pin QFN are shown in Figure 7, and tape
and reel dimensions are provided in Figure 8.
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 SKY13524-639LF 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,
Solder Reflow Information, document number 200164.
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.
