| 摘 要： | 随着太赫兹通信技术的发展，对于0.14 THz折叠波导行波管(FWTWT)的研究需求向着更高的功率和更宽的带宽发展。对双注行波管中的双路折叠波导慢波电路进行分析，得到不同参数下的高频特性变化规律。并对双路折叠波导慢波电路的功率分配和功率合成效率进行分析计算，得到功率合成效率96.3%。最后对双路慢波电路、功率分配/合成器和集中衰减器进行建模，并对注波互作用进行计算。在高压15 kV和单注电子的发射电流为40 mA条件下，得到0.14 THz频率下的合成输出功率为56 W，增益为31.4 dB，3 dB带宽为7 GHz。

| Abstract: | As the development of terahertz communication technology, the research for 0.14 THz Folded Waveguide Traveling Wave Tube(FWTWT) requires higher power and wider band. RF characteristics changes of two-circuit folded waveguide slow wave structure are analyzed with different structure parameters for two-beam traveling wave tubes. The power divider and the power combiner of two circuits folded waveguide are analyzed and calculated. The efficiency of the combined power is about 96.3%. The interaction calculation model is established, including two circuits folded waveguide slow wave, the power divider and the power combiner, and the attenuator. Under the condition of voltage 15 kV and single beam current 40 mA, the combined output power is about 56 W in 0.14 THz frequency, and the gain is 31.4 dB, 3 dB wideband is 7 GHz. |
