Product Description
The PE4231 SPDT High Power UltraCMOS™ RF Switch is designed to cover a broad range of applications from DC to 1.3 GHz. This single-supply reflective switch integrates on-board CMOS control logic driven by a simple, single-pin CMOS or TTL compatible control input. Using a nominal +3-volt power supply, a typical input 1 dB compression point of +32 dBm can be achieved. The PE4231 also exhibits input-output isolation of better than 42 dB at 1.0 GHz and is offered in a small 8-lead MSOP package.
