Abstract
Results of the analysis of the dimensional resonator based onmagnetostatic waves in epitaxial ferrite film (MSW-resonator) are discussed. A mathematicalmodel of such a resonator is based on the model of a Fabry-Perot, common in the case of thedispersion medium, with coupled elements in the form of microstrip transducers. Theformulas for calculating the weighted Q factor and the crosstalk attenuation is given. Theadvantage of two-port MSW-resonators as frequency set elements of generators is that they,along with great loaded Q are the phase shift, which can greatly exceed the value of ./2, asfor normal radio resonators, which significantly expands the range of frequency tuningwithout jumping of frequency microwave generators constructed by the ring scheme
