Abstract
An RF limiter circuit having an input terminal and an output terminal includes an RF propagation network having a first end coupled to the input terminal of the circuit and a second end coupled to the output terminal of the circuit. The RF limiter circuit further includes a plurality of diodes, each diode having an anode and a cathode with the anode of a first one of the diodes coupled to the RF propagation network and the cathode of a second one of the diodes coupled to the RF propagation network. The limiter circuit further includes a bias network for distributing a reverse bias voltage across each of the plurality of diodes and for providing a DC voltage on said RF propagation network.
