Abstract
The microwave signal generator includes a magnetron generating microwave signal. A filter filters a signal that may be a signal of the intrinsic oscillation frequency band of the magnetron, which is fed-back to the magnetron.
Claims20
A microwave signal generator comprising:
- a magnetron to generate a microwave signal;
- a coupler to receive the microwave signal generated by the magnetron and to send the microwave signal to a load;
- and
- a band-pass filter to receive the microwave signal from the coupler and to filter the microwave signal to obtain a signal from an oscillation frequency band of the magnetron, wherein the band-pass filter feeds the signal from the oscillation frequency band back to the magnetron in order to fix an oscillation frequency of the magnetron.

A microwave signal generator comprising:
- a magnetron integrally coupled to a load, wherein the magnetron generates a microwave signal;
- a coupler disposed within the load, wherein the coupler receives the microwave signal generated by the magnetron and sends the microwave signal to the load;
- and
- a band-pass filter for passing only the microwave signal of an intrinsic oscillation frequency band of the magnetron from the microwave signal received by the coupler and the microwave signal of the intrinsic oscillation frequency band is fed back to the magnetron.
1 more element
A microwave signal generator comprising:
- a magnetron to generate a microwave signal;
- a filter to receive the microwave signal from the magnetron and to filter the microwave signal to obtain a feedback signal from the microwave signal, wherein the filter feeds the feedback signal back to the magnetron which is used to fix an oscillation frequency of the magnetron.
