PE42420_14 Datasheet, PDF (1/12 Pages) Peregrine Semiconductor – UltraCMOS® SPDT RF Switch

Product Description
The PE42420 is a HaRP™ technology-enhanced
absorptive SPDT RF switch designed for use in 3G/4G
wireless infrastructure and other high performance RF
applications. It is ideal for transmit path switching, RF and
IF signal routing, AGC loops, and filter bank switching
applications.
This general purpose switch is comprised of two symmetric
RF ports and has exceptional port to port isolation up to
6 GHz. An integrated CMOS decoder facilitates a two-pin
low voltage CMOS control interface. In addition, no
external blocking capacitors are required if 0V DC is
present on the RF ports.
The PE42420 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.
