中文摘要:
      基于同轴波导径向合成器提出了一款可用于太赫兹频段的任意路数功率合成器。该功率合成器采用二阶阶梯变换结构,实现电场方向从同轴轴向到径向的扩散传播,并通过径向外围均匀分布的Y型功分结构实现任意路数功分。以D波段五路功率合成器为例,采用背靠背测试,在130 GHz到150 GHz频带内,背靠背插入损耗优于2 dB,带内回波损耗优于15 dB。由于是背靠背测试,因此该功率合成器单边损耗约为0.72 dB,折合合成效率为84.7%。
英文摘要:
      Based on coaxial-waveguide radial combiner, a broadband arbitrary-way power combiner in the terahertz band is proposed. In this model, the second order ladder transforming structure is utilized to change the direction of the electric field from the coaxial to the radial direction, and an equally distributed Y-junction is adopted to realize the arbitrary-way dividing. A 5-way coaxial-waveguide combiner is implemented in D band for testing. The back-to-back measurement results show that the return loss and the insertion loss within the bandwidth from 130 GHz to 150 GHz are less than 15 dB and 2 dB, respectively. Thus, the transmission loss of the combiner is about 0.72 dB and the combining efficiency is 84.7%.
