Peregrine Launches 75-Ohm RF Switch For Broadband Applications

San Diego -- Peregrine Semiconductor, a supplier of RF CMOS integrated circuits, announced availability of the RoHS-compliant PE42742 high-performance RF switch for broadband applications. Designed to exceed FCC 15.115 regulations, this 75-Ohm Single-Pole, Double-Throw (SPDT) device offers isolation of 88 dB @ 216 MHz and 78 dB @ 806 MHz. A design feature allows the device to maintain its isolation levels even in the un-powered state, which is one of the requirements of FCC compliance for CATV to antenna isolation.

"The PE42742 showcases the exceptional linearity and isolation benefits of UltraCMOS(TM), which enables high-value, innovative RF ICs with outstanding performance for the broadband industry," said Rodd Novak, Peregrine's Vice-President of Marketing. "This product addresses the technical challenges of the DTV, TV and DVR industries, and has received excellent response from engineers designing for these end-products. Further, the high-performance UltraCMOS foundation has made the PE42742 a viable solution for other types of broadband applications," he added.

PE42742 features high IIP3 (50 dBm @ 5 MHz-1 GHz); high IIP2 (90 dBm @ 5 MHz-1 GHz); CTB of -90 dBc; and high ESD tolerance of 1.0 kV HBM. The device also offers "terminated" and "closed" unpowered modes making it suited for any DTV, TV, DVR or set-top box where reflected signals in the off state can distort local images or for DVR and gaming platforms where the CATV signals must pass through the unit when unpowered.

The PE42742 is available in the 4x4mm 20-lead QFN package. Products samples and volume production are available now through Peregrine and its worldwide distribution partner, Richardson Electronics.
