从理论上得到了一般圆形谐振腔的耦合系数和内微扰引起的双模谐振频率偏移。它们被用于设计一个两级BPF连同外部Q也从理论上推导。以简单的形式分析了通带两侧固有衰减极点的频率和出现条件。
The coupling coefficient and resonant frequency shift of dual modes induced by the internal perturbation are obtained theoretically for a general circular resonator. They are used for the design of a two-stage BPF together with the external Q also theoretically derived. The frequency and the appearance condition of the intrinsic attenuation poles at both sides of the passband are analyzed in a simple form.
