RF SPDT switch delivers high linearity, ultra-fast settling time
San Diego, Calif. — Peregrine Semiconductor Corp. has introduced the PE42552 SPDT 50-ohm RF switch for test and measurement applications that require ultra-linear RF performance and ultra-fast settling time such as automated test equipment (ATE), RF/IF transceiver signal switching, filter bank switching and discrete DSA stages.

The PE42552, designed on Peregrine's HaRP-enhanced UltraCMOS silicon-on-sapphire process technology, is said to maintain excellent broadband RF performance from 9 kHz up to 7.5 GHz without gate lag and phase drift, and ensures fast switch-settling time. Peregrine said the PE42552 delivers the industry's fastest settling time and the highest linearity performance available in a RF broadband solid-state switch.

The PE42552 exhibits isolation of 47 dB at 3.0 GHz and approaches 30 dB at 7.5 GHz. The RF switch offers high ESD tolerance of 1.0 kV HBM on all ports, and an IIP3 of +65 dBm. The device is available in a RoHS-compliant, 16-lead, 3 x 3 x 0.75-mm QFN package.

Peregrine is exhibiting at the IEEE MTT International Microwave Symposium, in Atlanta, Ga., June 16-19, at Booth #1606.

Pricing: $3.34 in quantities of 100,000.
Availability: Sampling in July 2008.
