The PE45361 is Peregrine Semiconductor’s UltraCMOS® power limiter designed to operate in the 10 MHz to 6 GHz frequency range for use in wireless infrastructure transceivers and antennas, and in test and measurement applications. This HaRP™ technology-enhanced power limiter delivers low insertion loss and high linearity under non-limiting power levels and extremely fast response time in a limiting event, ensuring protection of sensitive circuitry. It also offers excellent ESD rating and ESD protection.
Unlike traditional PIN diode solutions, the PE45361 achieves an adjustable input 1dB compression point or limiting threshold via a low current control voltage (VCTRL), eliminating the need for external bias components such as DC blocking capacitors, RF choke inductors, and bias resistors. The limiter is also manufactured on Peregrine’s UltraCMOS® process.
