A miniature monoblock bandpass filter with combline‐type, quarter‐wavelength, and capacitive coupling is investigated. The coupling analysis and equivalent circuit consist of the 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 (Zr 0.8 , Sn 0.2 )TiO 4 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. © 2001 John Wiley & Sons, Inc.
