正交环耦合YIG电调滤波器设计分析

本文用等效电路分析了环耦合YIG电调滤波器,由于引入了合理的耦合环自感计算公式,从而得到了多级环耦合YIG滤波器的实用公式。根据此公式给出了二级滤波器设计例子。同时,分析了单级振子YIG滤波器中耦合环参数对通带响应的影响。

DESIGN ANALYSIS FOR AN ORTHOGONAL-LOOP-COUPLING YIG TUNABLE FILTER

An orthogonal-loop-coupling YIG tunable filter is analyzed by using the equivalent circuit. By introducing a suitable expression for the self-inductance of the coupling loop, applicable formulae for designing multi-stage YIG filters are given. Using these formulae, an example for designing the two-stage filter is presented. Also, the influence of the parameters of the coupling loops on the passband response is analyzed for a single-stage YIG resonance filter.
