| Number | Title | Issue Date |
| 8040189 | Microwave system for driving a linear accelerator A microwave system for driving a linear accelerator is provided. The inventive microwave system employs a plurality of magnetrons, at least one pulse generator to energize the magnetrons, means for synchronizing outputs from the magnetrons, and at least one waveguid... | 10/18/2011 |
| 7863988 | Microwave signal generator A microwave signal generator includes 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... | 01/04/2011 |
| 5515011 | Pulsed magnetron circuit with phase locked loop A semiconductor diode is connected across the cathode-to-anode path of a magnetron and through a storage capacitor and collector resistor to a supply voltage for enabling charging of the capacitor. A control pulse causes a switching transistor to conduct ... | 05/07/1996 |
| 5107272 | Radar system employing injection locked transmitter stage A radar transmitter chain employing injection locked oscillator, e.g., a magnetron, as an output stage. Problems arise with maintaining the injection locking bandwidth centered on the radar source transmit frequency. This alignment is maintained by allowi... | 04/21/1992 |
| 4961058 | Feedback stabilization loop Stabilizing a signal generating source by coupling a small amount of the output power through a bandpass filter tuned to the desired frequency and injecting the power back into the source. In another embodiment the filtered power may be increased by injec... | 10/02/1990 |
| 4823133 | Radar system The invention relates to a radar system comprising a transmitter with a periodically tunable HF-transmitter tube, as a magnetron with rotating tuning body, and a receiver with a mixing stage, in which echo pulses caused by transmitted radar pulses are mix... | 04/18/1989 |
| 4809004 | Crystal controlled magnetron The invention comprises a weather radar system in which a magnetron transmitter is controlled in frequency by injecting therein a low power locking signal from a stable frequency source. Frequency lock between the source and the magnetron is maintained wi... | 02/28/1989 |
| 4682178 | HF arrangement The invention relates to a coherent radar comprising a magnetron (10), a modulator (12) for pulsed driving if the magnetron, a stable local oscillator (22) and mixer (20) for producing an intermedicate frequency signal of incoming echoes and an intermedia... | 07/21/1987 |
| 4571552 | Phase-locked magnetron system Phase locking of the output signal of a magnetron with a frequency source signal is obtained by a phase comparison of the output signal and source signal to obtain an error signal which energizes a winding of the magnetron magnet to thereby change the flu... | 02/18/1986 |
| 4389594 | Device for electronically tuning a power magnetron The anode cavity of a power magnetron is connected through a coupling slot to a reactively terminated waveguide structure containing one or more selectively magnetizable ferrite elements acting as adjustable differential phase shifters for two microwave c... | 06/21/1983 |
