Overview
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.
