| Abstract: | The structure and the performance of L band VCO and the resonating cavity are described in this paper. Its osillating frequency can be tunned in the range of 0.9-1.07GHz, and its output power is more than 10mW. It can operate in scan frequency mode by using a sawtooth generator. The sample cavity is a square gap resonator. When a cylindrical sample is inserted into the cavity, the resonating frequency changes only a little. The microwave energy is fed to the cavity by magnetic coupling. While changing the distance between the coils and the cavity the coupling degree can be changed. |
