PE42721_15 Datasheet, PDF (1/12 Pages) Peregrine Semiconductor Corp. – SPDT RF Switch

Product Description
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.
