Abstract
In this paper, a novel design method for a dual-band bandpass fllter (BPF) with arbitrary controllable bandwidths based on a simple frequency mapping function is proposed and its analytical design equations are also derived. The circuit conversion techniques are employed for implementation with distributed transmission line. To validate the proposed dual-band BPF with controllable bandwidths, a low temperature co-flred ceramic (LTCC) transmission line as well as microstrip lines are used, respectively. The two types of design for the dual-band BPF have the same and signiflcantly difierent fractional bandwidths (FBWs), respectively. The flrst type of dual- band BPF with same FBWs are implemented at 2.11{2.17 and 3.45{ 3.55GHz. The second type of dual-band BPF with difierent FBWs are implemented at 3.40{3.60 and 5.15{5.25GHz. The measured and theoretical results show good agreement, signiflcantly validating the proposed frequency mapping function methodology.
