摘要：
In this paper, a miniaturized UWB Bandpass filter using a hybrid lumped capacitors - distributed transmission lines topology is designed. The filter design rules are carried out and a filter is optimized for a 3 dB fractional bandwidth of 127% with criteria of compacity, matching and selectivity. A sensitivity study versus critical parameters is also given. The filter length is reduced to 0.18 lambda @ 6.5 GHz in comparison with 0.54 lambda for the distributed topology. The selectivity is improved with a shape factor equal to 1.28:1 instead of 1.46:1.
