UltraCMOS® SP4T RF Switch

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-compatible four-throw version of the PE42451 with a wider frequency and power supply range. It is comprised 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.
