摘要

美国海军研究实验室目前正在研究将陀螺放大器作为毫米波雷达的高功率宽带源。三腔ka波段回旋速调管的峰值输出功率为225 kW，带宽为0.82%。在w波段，实验证明了几种多腔陀螺放大器。一种四腔回旋速调管放大器以34%的效率和370 MHz的带宽实现了84 kW的峰值输出功率。五腔回旋速调管的峰值输出功率为72 kW，带宽为410 MHz，饱和增益为50 dB。对于需要更大带宽的应用，回旋调强放大器也在研究之中。四段w波段回旋回旋管在925 MHz带宽下显示了50 kW的峰值输出功率。

Experimental demonstration of high power millimeter wave gyro-amplifiers

The Naval Research Laboratory is currently investigating gyro-amplifiers as high power, broadband sources for millimeter wave radars. A three-cavity Ka-band gyroklystron achieved 225 kW peak output power with 0.82% bandwidth. At W-band, several multi-cavity gyro-amplifiers have been experimentally demonstrated. A four-cavity gyroklystron amplifier has achieved 84 kW peak output power at 34% efficiency with 370 MHz bandwidth. A five-cavity gyroklystron demonstrated 72 kW peak output power with 410 MHz bandwidth and 50 dB saturated gain. For applications requiring greater bandwidth, gyrotwystron amplifiers are also under study. A four section W-band gyrotwystron demonstrated 50 kW peak output power at 925 MHz bandwidth.
