ABSTRACT:
The variation in the external bandwidth of input and output resonators of YIG filters and of single resonator device, is corrected by means of frequency selective impedance transformers. The transformers are comprised of specific impedance transmission lines which may be incorporated as integral parts of the YIG filter RF circuit.
