The PE45361 is a HaRP™ technology-enhanced power limiter designed for use in high performance power limiting applications in test and measurement (T&M) equipment and wireless-infrastructure transceivers and antennas. Unlike traditional PIN-diode solutions, the PE45361 achieves an adjustable input 1 dB 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.
