结合高功率输出和宽带宽的毫米波放大器将在需要具有重要信息内容的高功率无线电信号的领域实现显着改进。然而，迄今为止，唯一可用的器件要么是带宽有限的高功率真空电子器件，要么是低功率输出的大带宽半导体放大器。在这里，我们展示了一种新的真空电子行波管放大器设计，其测量输出功率为107 W， 3db带宽为6 GHz，以200 GHz为中心。该放大器的功率带宽积为642 W-GHz。这些结果提供了具有显著带宽的高功率毫米波源的演示。该器件易于扩展到其他频段，特别是100 GHz至1太赫兹的毫米波和亚毫米波频段。
A millimeter (mm) wave amplifier that combines both high-power output and a wide bandwidth would enable dramatic improvements in areas where high-power radio signals with significant information content are required. However, to date, the only available devices are either high-power vacuum electronic devices with limited bandwidths, or larger bandwidth semiconductor amplifiers with low-power output. Here, we show a new design of a vacuum electronic traveling-wave tube amplifier that has a measured output power of 107 W with a 3-dB bandwidth of 6 GHz centered on 200 GHz. The power-bandwidth product of this amplifier is 642 W-GHz. These results provide a demonstration of a high-power mm-wave source with significant bandwidth. This device is readily scalable to other frequency bands, particularly those in the mm- and sub-mm-wave frequency bands from 100 GHz to 1 THz.
