| Abstract: |
| An optimization method based on parameter sweep for the coupling hole
between the cavity,adjusting compensation structure of coupling loop for the inp
ut and output is proposed in this paper aiming at the problems of distunin
g and control accuracy of electrically tunable filters.By using the closed-loop
c
ontrol system combining the moving part with the software,an electrically tunabl
e filter with high tuning accury(25 kHz),narrow bandwidth(f0×0.25%
MHz,f0 is center frequency),high powe
r capacity(100 W) is designed.The fabricated filter has b
een applied to the engineering applications and exhibited good prospects. |
