Peregrine Semiconductor Corp. (China) (NASDAQ: PSMI) has debuted its new line of UltraCMOS® RF power limiters, including PE45140 and PE45450 slated for release in May. Peregrine’s power limiters represent the industry’s 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.
Of particular interest to RF designers, Peregrine’s power limiters save PCB space with a small form factor, reduce BoM (bill of materials) by eliminating the need for extra components, and improve time to market by reducing in-design time and costs. They also beat existing solutions in RF performance, including higher linearity to eliminate signal distortion, high ESD to ensure high reliability, wide bandwidth to enable design flexibility and fast response and recovery times to ensure robust protection of power-sensitive components. Finally, because Peregrine’s power limiters are based on UltraCMOS instead of GaAs, they can be closely integrated with other UltraCMOS RF components.
Peregrine’s UltraCMOS power limiters can protect:
- RF ports in test-and-measurement equipment.
- RF front ends and low-noise amplifiers (LNAs) in LMRs.
- RF receivers in wireless-infrastructure equipment.
- Tactical radio receivers from intentional jammers in military warfare.
- Transceiver (TRX) modules in radar systems.
