Product Description
The PE45140 is a HaRP™ technology-enhanced RF power limiter designed for use in tactical and military communications receivers, land mobile radio 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.
