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 Peregrine’s

insulator (SOI) technology on a sapphire substrate.

Peregrine’s HaRP™ technology enhancements deliver

high linearity and excellent harmonics performance. It is

the performance of GaAs with the economy and

integration of conventional CMOS.
