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.
