The PE42540 is a HaRP™-enhanced Absorptive SP4T RF switch developed on UltraCMOS® process technology. This switch is designed specifically to support the requirements of the test equipment and ATE market. It is comprised of four symmetric RF ports and has very high isolation. An on-chip CMOS decode logic facilitates a two-pin low voltage CMOS control interface and an optional external Vss feature. High ESD tolerance and no blocking capacitor requirements give this switch excellent integration and ruggedness.
