Introduction

The PE45140 is a HaRP technology-enhanced RF power limiter designed for use in tactical and other high performance power limiting applications. Unlike traditional PIN diode solutions the limiting threshold can be adjusted through a low current control voltage (VCTRL), eliminating the need for external components such as DC blocking capacitors, RF choke inductors, and bias resistors. This power limiter has symmetric RF ports that limit incident power up to 50W pulsed in both biased and unbiased conditions. It provides an extremely fast limiting response to undesired high power signals while delivering low insertion loss and high linearity under safe operating power levels. The PE45140 is manufactured on Peregrine’s UltraCMOS process, a patented variation of silicon-on-insulator (SOI) technology on a sapphire substrate. Peregrine’s HaRP technology enhancements deliver high linearity and excellent harmonics performance.
