The PE42641 is a HaRPTM-enhanced SP4T RF Switch developed on the UltraCMOSTM 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 HaRPTM technology enhancements deliver high linearity and exceptional harmonics performance. It is an innovative feature of the UltraCMOSTM process, providing performance superior to GaAs with the economy and integration of conventional CMOS.
