Noise Suppression and Precise Phase Control of a Commercial S-Band Magnetron
We demonstrate noise suppression and precise phase control of a commercial 2.45GHz magnetron aiming for wireless power transfer application. The impurity of the microwave spectrum was confirmed to be due to the switching frequency of 76kHz in the power ...
