Peregrine Semiconductor Corp. has introduced the PE42552 SPDT 50 RF switch for test and measurement applications that require ultralinear RF performance and ultrafast settling time such as 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 9kHz up to 7.5GHz 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 47dB at 3GHz and approaches 30dB at 7.5GHz. The RF switch offers high ESD tolerance of 1kV HBM on all ports, and an IIP3 of 65dBm. The device is available in a RoHS-compliant, 16-lead, 3mm x 3mm x 0.75mm QFN package.

Pricing starts at $3.34 in quantities of 100,000. Sampling will start in July.
