The PE42641 is a HaRP enhanced SP4T RF switch, available from Richardson Electronics, developed on the UltraCMOS process technology. The PE42641 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.

The PE42641 is also suitable for antenna band switching and switchable matching networks for cellular and non-cellular mobile applications. The PE42641 integrates on-board CMOS control logic with a low voltage CMOS-compatible control interface and requires no DC blocking capacitors.

This RoHS-compliant partis available in a standard 3x3x0.75mm QFN package. Peregrine’s HaRP technology enhancements deliver high linearity and exceptional harmonics performance.

The PE42641 is an innovative feature of the UltraCMOS process, providing performance better to GaAs with the economy and integration of conventional CMOS.
