PE42641 Datasheet, PDF (1/9 Pages) Peregrine Semiconductor Corp. – SP4T UltraCMOS RF Switch DC - 3.0 GHz

Product Description
The PE42641 is a HaRP™-enhanced SP4T RF Switch
developed on the UltraCMOS™ process technology. This
switch contains 4 identical WEDGE/CDMA compliant TX paths
and can be used in various GSM and WCDMA mobile
applications as well as other wireless applications up to
3000MHz. It is also suitable for antenna band switching and
switchable matching networks for cellular and non-cellular
mobile applications. It integrates on-board CMOS control logic
with a low voltage CMOS-compatible control interface and
requires no DC blocking capacitors. This RoHS-compliant part
is available in a standard 3x3x0.75mm QFN package.
Peregrine’s HaRP™ technology enhancements deliver high
linearity and exceptional harmonics performance. It is an
innovative feature of the UltraCMOS™ process, providing
performance superior to GaAs with the economy and
integration of conventional CMOS.
