Peregrine Semiconductor Corp., founder of RF SOI (silicon on insulator) and pioneer of advanced RF solutions, introduces the UltraCMOS PE42721 75-Ohm RF switch for designers of digital TV (DTV) tuner modules, cable TV (CATV) signal switching and distribution systems, multi-tuner digital video recorders (DVRs) and set-top boxes. The switch is ideal for geographic markets – such as China, Japan, Korea and Latin America – where broadband-TV devices must accommodate multiple RF inputs for cable, satellite and terrestrial reception while avoiding interference between these signals.
