END OF LIFE (EOL)
This product is currently going through the EOL process. It has a last-time buy date of January 27, 2023 and a final ship date of July 27, 2023. Replace with PE45450. For more information, please contact your local sales representative.
The PE45140 is a HaRP™ technology-enhanced RF power limiter designed for use in tactical and military communications receivers, land-mobile-radio (LMR) and other high performance power limiting applications. 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.
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.
