The PE42672 is a HaRP™-enhanced SP7T
RF Switch developed on the UltraCMOS™
process technology. It addresses the specific
design needs of the Quad-Band GSM Handset
Antenna Switch Module Market for use in
GSM/EDGE/PCS/DCS/WCDMA handsets.
The switch is comprised of three TX ports and
four RX ports. TX1 is designed for WCDMA
and TX2 and TX3 are designed for GSM/
EDGE. The four symmetric RX ports can be
used for GSM/EDGE/PCS RX. On-chip CMOS
decoder logic facilitates three-pin low voltage
CMOS control, while high ESD tolerance of
1500 V at all ports, no blocking capacitor
requirements, and on-chip SAW filter over-
voltage protection devices make this the
ultimate in integration and ruggedness.

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.
