The PE42542 is a HaRP™ technology-enhanced
absorptive SP4T RF switch designed for use in Test/
ATE, microwave and other wireless applications. This
broadband general purpose switch maintains excellent
RF performance and linearity from 9 kHz through
18 GHz. The PE42542 exhibits low insertion loss,
high isolation performance and has fast settling time.
No blocking capacitors are required if DC voltage is
not present on the RF ports.
The PE42542 is manufactured on Peregrine’s
UltraCMOS® process, a patented variation of silicon-on-
insulator (SOI) technology on a sapphire substrate.
Peregrine’s HaRP technology enhancements deliver high
linearity and excellent harmonics performance. It is an
innovative feature of the UltraCMOS process, offering the
performance of GaAs with the economy and integration
of conventional CMOS.
