SKY12248-492LF

2.3 to 4.2 GHz 120 W High-Power SPDT Switch

The SKY12248-492LF is a compact single-pole, double-throw (SPDT) fail-safe switch for TDD 4G and 5G applications. It can be tuned to specific RF bands within the range of 2.3 to 4.2 GHz by modifying select external SMT components.

This device features high-power handling at hot, low TX and RX insertion loss, and high isolation with low DC power consumption.

The device requires minimal external components, enabling a smaller PCB footprint.

The device is provided in a 5 × 5 mm, 20-pin Quad Flat No-Lead (QFN) package.

Pin-to-pin compatible with SKY12255 (160 W fail safe switch).
