PE42641 Datasheet, PDF (1/8 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 3000 MHz. 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 3 x 3 x
0.75mm 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.
