PE42442 Datasheet | pSemi

Product Description The PE42442 is a HaRP™ technology-enhanced absorptive SP4T RF switch designed for use in 3G/4G wireless infrastructure and other high performance RF applications. This switch is a pin-patible four throw version of the PE42451 with a wider frequency and power supply range. It is prised of four symmetric RF ports with very high isolation up to 6 GHz. An integrated CMOS decoder facilitates a two- or three-pin 1.8V CMOS control interface. In addition, no external blocking capacitors are required if 0 VDC is present on the RF ports. The PE42442 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.
