SKY13522-644LF

0.7 to 6.0 GHz High Isolation (Single Bit Control) SPDT Switch

Please note: SKY13522-644LF is being discontinued and is not recommended for new designs. The suggested replacement is SKY13446-374LF

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.
