Limiters protect phased array radars from permanent self inflicted damage when the radar transmits signal leaks into the receiver. However, next generation radars have increased transmit power and existing limiters are not able to protect the receivers. Therefore more robust limiters which can handle the transmitted power are needed. These limiters must also be low cost and in a form factor compatible with integration with shipboard radar systems. Our proposed solution uses a GaN based MMIC as a solution.
