摘要

本文介绍了一种具有衍射输出的高效可调相对论磁控管（HTRMDO），并对其进行了数值研究。为了提高调谐带宽和功率效率，谐振腔的外半径和磁场同时变化。仿真结果表明，HTRMDO 的调谐范围在 1.280 至 2.430 GHz 之间，调谐带宽为 62.0%，中心频率为 1.855 GHz。在调谐范围内，最大功率效率为 71.9%，最小功率效率为 36.0%，符合 3 dB 原则。此外，其输出模式恒定为 TE31。这是连续可调相对论磁控管在调谐带宽和功率效率方面的最高纪录。

A high-efficiency tunable relativistic magnetron with diffraction output

In this paper, a high-efficiency tunable relativistic magnetron with diffraction output (HTRMDO) is presented and studied numerically. To increase the tuning bandwidth and power efficiency, the outer radius of the resonant cavity and the magnetic field are simultaneously varied. The simulation results show that the HTRMDO has a tuning range between 1.280 and 2.430 GHz, corresponding to a tuning bandwidth of 62.0% with a center frequency of 1.855 GHz. In the tuning range, the maximum power efficiency is 71.9% and the minimum power efficiency is 36.0%, which complies with the 3 dB principle. Moreover, its output mode remains constant as TE31. This is a record tuning bandwidth and power efficiency for the continuously tunable relativistic magnetron.
