Abstract

Filters are widely used in communication systems and EMC equipment. We consider about the mixed lumped and nonuniform distributed circuit band-pass filter using nonuniform transmission line (NTL-PR) represented with lumped parallel resonance circuit, uniform transmission line and lumped π-type Brune section with negative sign. First, the simple equivalent circuit of the NTL-PR is shown. It can be represented with an imaginary gyrator and a lumped capacitor. Next, the design method for the mixed lumped and nonuniform distributed circuit band-pass filter is shown. The design method uses the simple equivalent circuit. Finally, examples of the transmission characteristics of the band-pass filters are shown
