PE42641数据手册RF/IF射频/中频RFID的射频开关规格书PDF

描述 Description

The PE42641 is a HaRP™-enhanced SP4T RF switch developed on the UltraCMOS® process technology. This switch contains four 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 × 3 × 0.75 mm QFN package.
