The PE45361 is a HaRP™ technology-enhanced power limiter designed for use in high performance power limiting applications in test and measurement equipment and wireless infrastructure transceivers and antennas.
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.
It 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.
The PE45361 is manufactured on Peregrine’s UltraCMOS® process, a patented advanced form of silicon-on-insulator (SOI) technology, offering the performance of GaAs with the economy and integration of conventional CMOS.
