摘要

本文介绍了一种w波段四波束平面积分行波管（TWT）。基于平面集成行波管的设计理念，本研究着重于利用弯曲FWG的高效电路，并通过使用传统PPM系统制造管来验证。利用所提出的平面集成周期性永磁体（PIPPM）对四波束行波管进行了进一步的研究，导致了其开发，组装和测试。实验结果表明，通过120 mm长的隧道，传输效率超过85%，验证了该光束光学系统的配置。该器件在12.6 kV工作电压下，最大饱和输出功率为10 W，饱和增益为23 dB，每通道带宽为6 GHz。四波束行波管具有一致的电性能，为短波毫米波行波管有源相控阵应用提供了一种新颖的解决方案。

Demonstration of a Four-Beam Integrated Travelling Wave Tube in W-Band

This letter presents an investigation into a W-band four-beam planar-integrated traveling wave tube (TWT). Building on the design concept of the planar integrated TWT, this research focuses on the high-efficiency circuit that utilizes a bending FWG, verified through the fabrication of a tube employing a conventional PPM system. Further research on the four-beam TWT utilizing the proposed planar integrated periodic permanent magnet (PIPPM) led to its development, assembly, and testing. Experiment results achieved over 85% transmission efficiency through a 120 mm long tunnel, validating this beam optical system configuration. The device attained a maximum saturated output power of 10 W and a saturated gain of 23 dB, with a bandwidth of 6 GHz per channel at an operating voltage of 12.6 kV. The four-beam TWT demonstrates consistent electrical performance and offers a novel solution for short-wavelength millimeter-wave TWT active phased arrays applications.
