Abstract
The input impedance of a circulator with an inphase eigen excitation resonator can be expressed by that of a 2-stage bandpass filter. The external Q factor of an inphase eigenexcitation resonator should be three-quarters that of rotational-phase eigen-excitation resonators to obtain a maximally fiat performance.
