This paper describes bandpass filters using linear tapered transmission line resonators (LTLR's). Bandpass filters are designed on the basis of the approximate description of LTLR's with cascaded multi-sections of uniform transmission lines whose widths are slightly different. By this design method, the fundamental characteristics of LTLR's and filter design parameters can be easily obtained using a general-purpose microwave circuit simulator. Trial LTLR bandpass filters showed excellent performance such as low insertion losses and the ability to control spurious responses, then their measured responses indicated close correspondence with the design results.
