Abstract

A compact multi-band bandpass filter design with low- temperature co-fired ceramic (LTCC) technology is proposed in this paper. Using divided combline resonators with grounded and coupled capacitors, dual-band (2.4 GHz and 5.5 GHz) and tri- band (2, 4 and 7 GHz) bandpass filters are obtained. Moreover, while the number of the pass bands increase, the volume of the filter remains almost unchanged. The theoretical analysis of the prototype filters is described in the paper. The measurement and layouts of fabricated components are also presented.
