Ferrite Power Limiter for Radio Set AN/GRC-144.

Abstract

This investigation describes analytical and experimental results obtained on a C-band ferrite limiter which utilizes a YIG rod inserted along the longitudinal axis of a coupled dielectric resonator bandpass structure. This device is aimed at providing receiver front-end protection for communication systems such as the AN/GRC-144 which operate in a dense, high signal power environment. By utilizing a long, thin, single crystal YIG rod instead of YIG spheres, the limiter dynamic range has been extended from 20 dB to 35 dB. The threshold power varies from 5 dBm at 4.4 GHz to 15 dBm at 5.0 GHz with an insertion loss of less than 1.0 dB across the band. (Author)
