Abstract

A miniature monoblock bandpass filter with combline-type, quarter-wavelength, and capacitive coupling is investigated. The coupling analysis and equivalent circuit consist of tire transmission lines, and lumped elements are presented to predict the filter performance. A filter design technique based on the results of the equivalent-circuit parameters is described. A miniature monoblock bandpass filter using (Zr0.8, Sn0.2)TiO4 ceramics is fabricated at a center frequency of 1600 MHz. Excellent experimental results of the fabricated filter measured by an HP8510B network analyzer verify the design specification.
