SKY13523-639LF

0.7 to 3.0 GHz High-Isolation SP3T Switch

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.

Please note: SKY13523-639LF is being discontinued and is not recommended for new designs. The suggested replacement is SKY13586-678LF.
