The PE42448 is a HaRP™ technology-enhanced SP4T RF switch that supports a frequency range from 10 MHz to 6 GHz. It delivers extremely low insertion loss and high linearity with high input power handling capability making this device ideal for hybrid analog beamforming and in 5G massive MIMO (multi-input multi-output) applications. No blocking capacitors are required if DC voltage is not present on the RF ports. The PE42448 is manufactured on pSemi’s UltraCMOS+ process, a patented advanced form of silicon-on-insulator (SOI) technology.
