Noise Suppression and Precise Phase Control of a Commercial S-Band Magnetron

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 supply. With the decoupling capacitor installed...
