The PE42451 is a HaRP™-enhanced absorptive SP5T RF switch developed on the UltraCMOS® process technology. This general purpose switch is comprised of five symmetric RF ports and has very high isolation. An on-chip CMOS decode logic facilitates a three-pin low voltage CMOS control interface and an optional external Vss feature (VssEXT). High ESD tolerance and no blocking capacitor requirements give this excellent integration and ruggedness.
