Product Description

The PE42423 is a HaRP™ technology-enhanced

absorptive 50Ω SPDT RF switch designed for use in high

power and high performance WLAN 802.11 a/b/g/n/ac

applications such as carrier and enterprise Wi-Fi Products,

supporting bandwidths up to 6 GHz.

This switch features high linearity which remains invariant

across the full supply range. PE42423 also features

exceptional isolation, high power handling and is offered in

a 16-lead 3x3 mm QFN package. In addition, no external

blocking capacitors are required if 0V DC is present on the

RF ports.

The PE42423 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.
