pSemi PE42724A-Z

The PE42724 is a HaRP technology-enhanced reflective SPDT RF switch designed for use in cable applications including DOCSIS 3.0/1 cable modem, set-top box and residential gateway. It delivers high linearity, excellent harmonics performance and high surge immunity in the 5–1794 MHz band. It also features low insertion loss and high isolation performance making the PE42724 ideal for DOCSIS 3.1 applications. The PE42724 is manufactured on Peregrine’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.
