PE4251MLI-Z Datasheet, PDF (1/10 Pages) Peregrine Semiconductor – UltraCMOS® SPDT RF Switch 10–4000 MHz, Absorptive

Product Description
The PE4251 is a HaRP™ technology-enhanced absorptive
single pole double throw (SPDT) 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 4 kV 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.
