Design and Stability Analysis of a Three-Gap Coupled Output Circuit with Three Modes Overlapping

摘要

The resonant characteristics and the mode overlapping process of a three-gap coupled cavity output circuit had been discussed. Based on an X-band three-gap coupled cavity output circuit, the group delay characteristic and working stability are simulated and studied. The results show that the output bandwidth of 6.61% at 1.7dB fluctuation in X-band may be obtained with three-mode overlapping and each mode can stably operate in the bandwidth.
