UltraCMOS® SPDT RF Switch 5–2200 MHz. The PE42721 is a HaRP™ technology-enhanced absorptive 75Ω SPDT RF switch developed on the UltraCMOS® process technology. PE42721 is a highly linear device delivering high isolation and very low insertion loss performance. It is designed for broadband applications such as TV tuner modules, CATV signal switching and distribution, DTV, multi-tuner digital video recorders (DVRs) and set-top boxes.
PE42721 supports +1.8V control logic and offers high ESD protection. PE42721 is pin compatible to PE42750. In addition, no blocking capacitors are required if DC voltage is not present on the RF ports. Peregrine’s HaRP™ technology enhancement is an innovative feature of the UltraCMOS® process, offering the performance of GaAs with the economy and integration of conventional CMOS.
