Evaluation Kit for the PE4251 switch. 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.
