@@@@An optimization method based on parameter sweep for the coupling hole between the cavity, adjusting compensation structure of coupling loop for the input and output is proposed in this paper aiming at the problems of distuning and control accuracy of electrically tunable filters . By using the closedloop control system combining the moving part with the software,an electrically tunable filter with high tuning accury (25 kHz),narrow bandwidth( f0 × 0 . 25% MHz, f0 is center frequency),high power capacity (100 W) is designed . The fabricated filter has been applied to the engineering applications and exhibited good prospects .
