PE42851

Product Description The PE42851 is a HaRP™ technology-enhanced SP5T high power RF switch supporting wireless applications up to 1 GHz. It offers maximum power handling of 42.5 dBm continuous wave (CW). It delivers high linearity and excellent harmonics performance. It has both a standard and attenuated RX mode. No blocking capacitors are required if DC voltage is not present on the RF ports. The PE42851 is manufactured on pSemi’s UltraCMOS® process, a patented variation of silicon-on-insulator (SOI) technology on a sapphire substrate, offering the performance of GaAs with the economy and integration of conventional CMOS.
