Dual differential RF switch offers matched channels to 6 GHz
PE42920 is a broadband and low loss device enabling the switching of two independent differential signals. it consumes less power than active differential switches and offers 2 kV HBM ESD protection. It has high isolation between same-channel inputs as well as opposite active channels. It has been designed for low phase mismatch between matched paths.
The swith is specified over 10 kHz–6 GHz; typical operating parameters include; insertion loss of 0.7 dB; isolation between same channels at 6 GHz of 26 dB; isolation between opposite active channels at 6 GHz of 30 dB; and phase mismatch between matched paths at 6 GHz of 15 degrees.
PE42920 is manufactured on Peregrine’s UltraCMOS process, a variation of silicon-on-insulator
(SOI) technology on a sapphire substrate, which the company positions as offering the performance of gallium arsenide with the economy and integration of conventional CMOS.
