摘要: 提出了相位关系和交叉耦合两种分析交叉耦合的模型;给出了在腔体滤波器中实现交叉耦合的方法,通过在非相邻谐振器之间开辟辅助信号通道并添加控制部件,引入有限的传输零点而优化了滤波器性能。基于提出的分析模型,设计实例验证了该方法的可行性与实用性。Abstract: Two models for analyzing both the cross-couplings and their phase relationships and the implementation in cavity-filters by establishing auxiliary signal passages and adding control parts between non-adjacent resonators to both introduce finite transmission zeroes and optimize the performance of filters are proposed. The feasibility and practicability of the method are validated by design examples based on the presented models.
