The PE42448 is a high?performance SP4T RF switch from pSemi, built on its patented UltraCMOS+™ silicon?on?insulator (SOI) process and enhanced with HaRP™ technology. It operates across a wide 10 MHz to 6 GHz frequency range and is designed for demanding RF applications.

Key benefits include very low insertion loss, high isolation, excellent linearity, and high input power handling, along with fast settling time for efficient RF signal routing. The device does not require blocking capacitors when no DC voltage is present on the RF ports, simplifying design.

These characteristics make the PE42448 especially well?suited for 5G massive MIMO systems and hybrid analog beamforming, where signal integrity, efficiency, and rapid switching are critical.
