Description
The SKY13523-639LF is a single pole, triple-throw (SP3T) switch
used for single-ended filter switching in cellular applications. The
SKY13523-639LF 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 three switched RF
outputs (RF1 to RF3) 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 SKY13523-639LF 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.
