QFN package

The PE42451 is a HaRP™-enhanced Absorptive SP5T

RF Switch developed on the UltraCMOS

® process

technology. This general purpose switch is comprised of

five symmetric RF ports and has very high isolation. An

on-chip CMOS decode logic facilitates a three-pin low

voltage CMOS control interface and an optional external

Vss feature (VssEXT). High ESD tolerance and no

blocking capacitor requirements make this the ultimate in

integration and ruggedness.

Peregrine’s HaRP™ technology enhancements deliver

high linearity and exceptional harmonics performance. It

is an innovative feature of the UltraCMOS

® process,

providing performance superior to GaAs with the

economy and integration of conventional CMOS.
