Product Description
The PE42920 is a dual differential single pole double
throw (DDSPDT) RF switch developed on Peregrine’s
UltraCMOS® process technology. It is a broadband and
low loss device enabling the switching of two
independent differential signals. This device 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 PE42920 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.
