摘　　要：提出一种新型双模扇形谐振腔,并使用该谐振腔设计一个双模谐振腔增益均衡器。该均衡器具有两层结构:上层为两个双模谐振腔,下层为基片集成波导传输线。设计了两个正交的耦合缝隙,通过主传输线在该谐振腔中同时激励起两个非简并模,并通过调节扇形的角度和微扰金属柱的位置实现独立调节其中一个模式的谐振频率;研究了薄膜电阻的加载位置,实现独立调节两个模式的Q值和衰减量。与单模谐振腔均衡器相比,减少一半数量的谐振单元,从而使得结构更加紧凑。最后加工了该均衡器,测量曲线和仿真曲线一致性较好。A novel dual-mode sector resonator is proposed and a gain equalizer is designed based on the non-degenerate dual-mode resonator. The equalizer has two layers with two resonators and sub- strate integrated waveguide. Two orthogonal coupling slots are designed to excite two non-degenerate modes in the cavity; perturbation vias are employed to perturb one of the dual-mode, which can tune resonance frequency of the mode. The positions of the film resistors loaded on resonator are investi- gated to realize independent tuning of attenuations and Q-factor of the dual-mode. Compared with e- qualizer based on single mode resonators, the proposed equalizer keeps the original performance with half of the resonators cut, and it has more compact volume. The measured results are in good agreement with the simulated results, indicating the proposed equalizer has a good application future.
