PE4249 Description
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 manded OFF. It also provides low insertion loss with extremely low bias requirements while operating on a single 3-volt supply.
