1. A high power limiter for a low noise amplifier, comprising a substrate, a first anti-parallel array of Schottky diodes monolithically integrated on said substrate and comprising first and second Schottky diodes arranged in parallel and in reverse polarity relative to each other between a first input node and a first output node, a conductor on said substrate having a first end providing a limiter input for receiving a signal and a second end providing a limiter output for connection to said low noise amplifier, said first input node being coupled to said conductor intermediate said first and second ends of said conductor, said first output node being coupled to a ground reference, a second anti-parallel array of Schottky diodes monolithically integrated on said substrate and coupled in series with said first anti-parallel array between said conductor and said ground reference, said second anti-parallel array comprising third and fourth Schottky diodes arranged in parallel and in reverse polarity relative to each other between a second input node and a second output node, said second input node being coupled to said first output node, said second output node being coupled to said ground reference.
