The PE4272 and PE4273 SPDT CATV switches are claimed to offer unprecedented price/performance ratio for the broadband market.

Peregrine Semiconductor has released the PE4272 and PE4273 SPDT CATV switches that offer unprecedented price/performance ratio for the broadband market.

Designed to replace complicated pin-diode-based designs, these new switches offer a simple, economical high-power switching solution by delivering high isolation and linearity, and maintaining that performance from below 1MHz to 3GHz.

"Our customers count on UltraCMOS technology to engineer leading-edge RF products which will shorten their design cycle and reduce their BOM; these two devices deliver", stated Rodd Novak, Vice President of Marketing for Peregrine.

"No other solid state devices can match this level of broadband performance, nor are as simple to design in", he continued.

The PE4272 and PE4273 switches feature: ultralow power, drawing 8uA at 3V; P1dB compression point of +32dBm; low insertion loss of 0.50dB at 1GHz; and incorporate a simple CMOS single pin interface.

The devices are offered in the small-footprint 6-lead SC-70 with 35dB of isolation at 1GHz (PE4273) and the 8-lead MSOP with 44dB of isolation at 1GHz (PE4272), making them ideal for PCTV, TV tuner, set-top box, satellite, DVR and cable applications.

The PE4272 is priced at $0.45 each and the PE4273 is priced at $0.30 each (10,000 units).

Both devices are in high-volume production and are available via Peregrine's worldwide distribution partner, Richardson Electronics.
