PE4251_14 Datasheet, PDF (1/9 Pages) Peregrine Semiconductor – SPDT UltraCMOS™ RF Switch

Product Description
The PE4251 is a HaRP™-enhanced Absorptive SPDT (single
pole double throw) RF Switch for use in general switching
applications and mobile infrastructure. This device offers a
flexible supply voltage of 3.3/5V, single-pin or complementary
pin control inputs, and 4kV ESD tolerance. It presents a simple
alternative solution to pin diode and mechanical relay switches.
Peregrine’s HaRP™ technology enhancements deliver high
linearity and exceptional performance. It is an innovative
feature of the UltraCMOS™ process, providing performance
superior to GaAs with the economy and integration of
conventional CMOS.
