Description
The SKY13321-360LF is a pHEMT GaAs FET I/C switch. The
switch may be used in transmit/receive applications by
connecting the RF common port (RFC, pin 7) to either the J1 or J2
port (pin 1 or 4, respectively) using a low loss path (i.e., a positive
voltage applied to either V1 or V2 pins).
The switch is manufactured in a compact, 2 x 2 mm, 8-pin
exposed pad plastic 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 SKY13321-360LF Evaluation Board is used to test the
performance of the SKY13321-360LF SPDT Switch. An assembly
drawing for the Evaluation Board is shown in Figure 9.
Package Dimensions
The PCB layout footprint for the SKY13321-360LF is provided in
Figure 10. Typical case markings are shown in Figure 11.
Package dimensions for the 4-pin QFN are shown in Figure 12,
and tape and reel dimensions are provided in Figure 13.
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 SKY13321-360LF is rated to Moisture Sensitivity Level 1
(MSL1) at 260 qC. It can be used for lead or lead-free soldering.
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, Discrete Devices and IC Switch/Attenuators
Tape and Reel Package Orientation, document number 200083.

NOTE: A semi-universal Evaluation Board is used to test the SKY13321-360LF.
Some RF lines are used to apply DC bias and have 0 Ω resistors installed. There
are two RF bypass capacitors added to the DC control lines. The RF paths -- RFC,
J1, and J2 -- have DC blocking capacitors installed.
