PE42420

Product Description The PE42420 is a HaRP™ technology-enhanced absorptive SPDT RF switch designed for use in 3G/4G wireless infrastructure and other high performance RF applications. It is ideal for transmit path switching, RF and IF signal routing, AGC loops, and filter bank switching applications. This general purpose switch is comprised of two symmetric RF ports and has exceptional port to port isolation up to 6 GHz. An integrated CMOS decoder facilitates a two-pin low voltage CMOS control interface. In addition, no external blocking capacitors are required if 0 VDC is present on the RF ports. The PE42420 is manufactured on pSemi’s UltraCMOS® process, a patented variation of silicon-on-insulator (SOI) technology on a sapphire substrate. pSemi’s HaRP technology enhancements deliver high linearity and excellent harmonics performance. It is an innovative feature of the UltraCMOS process, offering the performance of GaAs with the economy and integration of conventional CMOS. Figure 1.
