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 switch excellent integration and ruggedness. Peregrine?s HaRP? technology enhancements deliver high linearity and excellent harmonics performance with the economy and integration of conventional CMOS. 框图
