LONG LIFE K-BAND DUPLEXER
Abstract
Research was continued on the development of a long life K-band three part duplexer. Technical activities on the long life gas TR tube, semi conductor switch limiter and ferrite limiter resulted in experimental models and test data. The gas TR tube was measured at an incident power of 3.6 KW without keep alive, the spike energy was 2. ergs and tge flat power 75 milli watts. The semiconductor switch limiter efforts were successful when a PIN diode was used in the ridged waveguide test fixture. With DC bias a switch was operated from 22 to 24.5 GC with an insertion loss of 1.4 db maximum and an isolation of 28.4 db minimum, the power level was 1 milli watt. The same device was measured in the forward bias state (high isolation) at 1.KW incident power where the isolation was measured to be 30 db or greater. A ferrite limiter was measured with limiting in excess of 16 db. The insertion loss was 4 to 6. db. Preliminary multipactor units were constructed to test surface and multipacting, however, test data has not been obtained.
