Product Description
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 make this the ultimate in integration and ruggedness.
