摘要: The author has already reported a much more miniaturized split-ring resonator compared with the existing one-wavelength ring resonators by using microstrip lines and prototype two-stage tunable bandpass filter. In present paper, basic characteristics salient features of are summarized. Using general-purpose simulation program for analysis microwave circuits, calculating methods filter coupling parameters, derived generalized expression inverters, were described. design chart was constructed indicating concrete steps designing. Finally, three-stage 600-MHz band based on forementioned results designed fabricated, its operational presented. experimental agreed quite well computer simulation. validity method been confirmed. The filters have suitable structure high-frequency hybrid IC. They considered to be applicable over wide frequency in UHF SHF bands.
