PE4249 Datasheet (Peregrine Semiconductor)

PE4249, SPST CATV MOSFET Switch

The PE4249 is a high-isolation MOSFET Switch designed for CATV applications, covering a broad frequency range from DC up to 1.3 GHz.

This singlesupply SPST switch integrates a single-pin CMOS control interface, and is non-reflective at port RF1 and open reflective at port RF2 when commanded OFF.
