Abstract
A narrowband filter comprises an input terminal, an output terminal, and an array of basic resonator structures coupled between the terminals to form a single resonator having a resonant frequency. The resonator array may be arranged in a plurality of columns of basic resonator structures, with each column of basic resonator structures having at least two basic resonator structures. The basic resonator structures in each column may be coupled between the terminals in parallel or in cascade. Two or more resonator arrays may be coupled to generate multi-resonator filter functions.
