PE4280中文资料UltraCMOS® SPDT RF Switch数据手册pSemi规格书

描述 Description

The PE4280 is an UltraCMOS® switch designed for CATV applications, covering a broad frequency range from 5 MHz up to 2.2 GHz. This single-supply SPDT switch integrates a two-pin CMOS control interface. It also provides low insertion loss with extremely low bias requirements while operating on a single 3V supply. In a typical CATV application, the PE4280 provides for a cost effective and manufacturable solution when compared to mechanical relays.
