50W Power Limiter Protects 20 to 2000MHz

Peregrine Semiconductor’s PE45140 adjustable power limiter protects up to 50W pulsed RF inputRFMW, Ltd. announces design and sales support for Peregrine Semiconductor’s new, adjustable power limiter providing protection for up to 50W pulsed RF input. For CW applications, the PE45140 handles up to 10W of power. The adjustable power limiting threshold, from +22 to +32dBm, enables flexibility across different platforms and architectures. Peregrine’s UltraCMOS, monolithic solution is 8X smaller than comparable GaAs PIN diode solutions and no external components are required. The PE45140 maintains a 64dBm IIP3 for high linearity applications in LMR and public safety radios. Receiver protection in SDR tactical radios averts damage from intentional jammers or ESD strikes with an ESD HBM of 8000 volts. The Peregrine Semiconductor PE45140 offers instantaneous protection and rapid return that’s more 10x faster than PIN diode limiter designs.
