Introduction

The PE42452 is a HaRP technology-enhanced absorptive SP5T RF switch designed for use in 3G/4G wireless infrastructure and other high performance RF applications. This switch is a pin-compatible upgraded version of the PE42451 with 1.8V control logic. It is comprised of five symmetric RF ports and has very high isolation. An integrated CMOS decoder facilitates a three-pin low voltage CMOS control interface and an external negative supply option. In addition, no external blocking capacitors are required if 0V DC is present on the RF ports. The PE42452 is manufactured on Peregrine’s UltraCMOS process, a patented variation of silicon-oninsulator (SOI) technology on a sapphire substrate. Peregrine’s HaRP technology enhancements deliver high linearity and excellent harmonics performance. It is an innovative feature of the UltraCMOS process, offering the performance of GaAs with the economy and integration of conventional CMOS.
