Microwave bandpass filters with quarter-wavelength resonators

This report presents the proposal and synthesis design of microwave bandpass filters with quarter-wavelength (λ⁄4) stepped-impedance resonators (SIRs) on the basis of immittance inverters. Firstly, the bandpass prototype filter is proposed with identical terminations and alternative immittance inver...
