Product Description
The PE42821 is a HaRP⢠technology-enhanced high
power reflective SPDT RF switch designed for use in
mobile radio, relay replacement and other high
performance wireless applications.
This switch is a pin-compatible faster switching version of
the PE42820. It maintains high linearity and power
handling from 100 MHz through 2.7 GHz. PE42821 also
features low insertion loss and is offered in a 32-lead
5x5 mm QFN package. In addition, no external blocking
capacitors are required if 0V DC is present on the RF
ports.
The PE42821 is manufactured on Peregrineâs
UltraCMOS® process, a patented variation of silicon-on-
insulator (SOI) technology on a sapphire substrate.
Peregrineâs 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.
