UltraCMOS technology pushes devices above 13 GHz

The UltraCMOS process technology, developed by Peregrine Semiconductor, pushes device frequencies up to 13.2 GHz. The PE9308 Rad-hard prescaler, designed for space, high-performance military, and infrastructure applications, is the first CMOS device to operate in X and Ku bands, which is made possible by the UltraCMOS process.

The PE9308 operates at just 25 mA (typical) at 2.5 V, which the company claims is about 10% of the power of an equivalent GaAs device. Other features include fixed divide ratio of 4; low SSB phase noise; immunity to single event latchup; a single-event upset below 10E-9 errors/bit-day; and tolerance total dose radiation of 100 Krads.

The PE9308 is offered in an 8-lead formed flat pack or die, and is in production now. Evaluation kits are also available.

A second product pair is the PE4272 and PE4273 SPDT CATV switches for the broadband market. Designed to replace complicated pin-diode-based designs, these switches offer a simple, economical, high-power switching solution by delivering high isolation and linearity, and maintaining that performance from below 1 MHz through 3 GHz.

The switches feature ultra-low power, drawing 8 ╬ťA at 3 V and an insertion loss of 0.50 dB at 1GHz. They incorporate a simple CMOS single-pin interface. The parts are offered in small-footprint, 6-lead SC-70 packages with 35 dB of isolation at 1 GHz (PE4273) and 8-lead MSOP packages with 44 dB of isolation at 1 GHz (PE4272). The PE4272 is priced at $0.45 and the PE4273 sells for $0.30, both in lots of 10,000. Both devices are in high-volume production.
