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.
