Abstract

The results of modeling and measurements of the performance parameters of new configuration of the tunable 3-grids coupler combined with a quasi-optical mm-wave resonator are presented. By means of grid rotation and grid assembly shift, it is possible to control the output power of a Free Electron Maser (FEM) and tune its oscillation frequency accurately. The coupler was used to evaluate the quality parameters of the resonator by measuring the reflection coefficient S₁₁(f) of the resonator through the coupler. There is good agreement between theory and experiment.
