The PE42444 from pSemi is an SP4T RF Switch that operates from 1.8 to 5 GHz. This switch can handle an RMS input power of 10 W (40 dBm), a peak input power of 100 W (50 dBm), and has an insertion loss of 0.5 dB. It uses patented HARP technology enhancements to deliver high linearity of 85 dBm and excellent harmonics performance. The switch is manufactured on pSemi’s Ultra-CMOS (SOI) process and is available in a surface-mount 20-lead LGA package that measures 4 x 4 mm and is ideal for use in analog front-end for hybrid beamforming, 5G massive MIMO active antenna systems (AAS), and 4G/4.5G TD-LTE macro/microcell/RRH applications.
