Product Description
The PE42451 is a HaRP™-enhanced sbsorptive SP5T RF wwitch 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.
pSemi’s HaRP™ technology enhancements deliver high linearity and exceptional harmonics performance. It is an innovative feature of the UltraCMOS® process, providing performance superior to GaAs with the economy and integration of conventional CMOS.
