CMOS-on-insulator RF power limiters are alternative to discrete, PIN-diode circuits

April 09, 2014 // By Graham Prophet
Peregrine has used its UltraCMOS, CMOS-on-insulator technology to design power-limiters that outperform GaAs-based limiters in protecting systems from excessive RF Power, intentional jammers and ESD events

PE45140 and PE45450, for release in May 2014, are, Peregrine claims, the first turnkey, monolithic solutions to provide an alternative to discrete, PIN-diode limiters based on gallium arsenide (GaAs). UltraCMOS power limiters deliver simple, repeatable and reliable protection ideal for test-and-measurement, land-mobile-radio (LMR), wireless-infrastructure, military and radar systems.

On a chip eight times smaller than the board space required by discrete, PIN-diode solutions, Peregrine’s new power limiters provide a 10-100X improvement in response and recovery time; deliver greater than 40 dB improvement in linearity (IP3); and offer a 20X improvement in ESD (electrostatic discharge) protection.
