The PE4257 is a high-isolation SPDT Switch designed for RF applications, covering a broad frequency range from 5 MHz up to 3 GHz. This single-supply absorptive switch integrates a two-pin CMOS control interface. It also provides low insertion loss with extremely low bias requirements while operating on a single 3-volt supply.
