本研究的目的是调查光谱纯度的连续磁控管的微波功率传输系统的太阳能卫星，或其他无线电应用。测量了2.45GHz微波炉磁控管的振荡谱，并讨论了振荡谱的纯度。截止磁控管具有窄带宽。然而，在某些情况下，由于电源涟漪，振荡频谱具有FM噪声。注入锁定方法有助于降低FM噪声。
The objective of the present study is to investigate spectral purity of a CW magnetron for a microwave power transmission system of Solar Power Satellites, or other radio applications. Oscillation spectra of a 2.45GHz oven magnetron were measured and the purity of the spectra is discussed. A filament-off magnetron has narrow bandwidth. In some conditions, however, the oscillation spectrum has FM noise due to a power supply ripple. An injection locking method contributes to reducing the FM noise.
