Injection-Locked CW Magnetron for a wirelessly-powered TV

It is shown a wireless power transfer system that transmitted microwave drove the power and video signal of a TV which worked as a wirelessly-powered TV. At the transmitter, we modulated a video signal on a 2.45 GHz sine wave via frequency modulation, a 2.45 GHz injection-locked magnetron could amplify the frequency modulation signal. Utilizing injection locking method, we injected the modulated signal to a 2.45 GHz magnetron and the magnetron amplified this modulation signal. At the receiver, we rectified the microwave energy to the power source and demodulated this microwave to the video signal of the TV. The wireless power transfer distance was 3.5 meters. At the aid of the transmitted microwave, we successfully rectified 48 W DC power and demodulated the video signal.
