电子回旋加速微波量子放大器的不稳定性已被当作新型行波放大器的基础,这种新型行波放大器在毫米波长范围内以非常高的功率电平工作。这种放大器的第一个试验模型以35千兆赫的频率工作,试验表明其稳定增益为17分贝,输出功率为10千瓦(未饱和)。在>30分贝的动态范围内,增益是线性的。增益的绝对值及其对电流和磁场的依赖关系与理论计算的结果极为一致。带宽和饱和功率还必须直接测量,但没有发现什么妨碍成功地达到设计指标(即带宽≌10％,功率约为10~5瓦,效率>10％)的根本性问题。
The instability of the electron cyclotron microwave microwave amplifier has been taken as the basis of the new traveling-wave amplifier, which operates at very high power levels in the millimeter wavelength range. The first pilot model for this amplifier operates at 35 GHz, with tests showing a steady-state gain of 17 dB and an output power of 10 kW (not saturated). In the dynamic range of> 30 dB, the gain is linear. The absolute value of gain and its dependence on current and magnetic field are in good agreement with the theoretical calculations. The bandwidth and saturation power must also be measured directly, but no fundamental problems have been found that could hinder the successful achievement of design specifications (ie 带 10% bandwidth, about 10-5 watts, and> 10% efficiency).
