PE4235

www.DataSheet4U.com Product Specification PE4235 Product Description The PE4235 RF Switch is designed to cover a broad range of applications from near DC to 4000 MHz. This single-supply reflective switch integrates on-board CMOS control logic driven by a simple, single-pin CMOS or TTL control input. Using a nominal +3-volt power supply, a 1 dB compression point of +15 dBm can be achieved. The PE4235 also exhibits outstanding isolation of better than 40 dB at 1000 MHz and is offered in a small 3x3 mm DFN package. The PE4235 is manufactured on Peregrine’s UltraCMOS™ process, a patented variation of silicon-on-insulator (SOI) technology on a sapphire substrate, offering the performance of GaAs with the economy and integration of conventional CMOS.
