Abstract
A novel super compact microwave ultra-wideband (UWB) bandpass passive filter (BPF) is proposed using S-shape broadside-coupled striplines. A theoretical model is presented to analyze the scattering and coupling mechanism of the suggested filter. To eliminate interference, a tunable integrated notched-band filter is also introduced using a new technique. A group delay of 0.08 ns within the passband is observed. Experiments carried out over the designed examples and the measurement and simulation results are compared. The physical volume of the filter is 1.5 mm × 1.8 mm × 1.5 mm.
提出了一种新型的超紧凑微波超宽带(UWB)带通无源滤波器(BPF)，该滤波器采用s型宽带耦合带状线。提出了一个理论模型来分析该滤波器的散射和耦合机理。为了消除干扰，采用一种新技术，引入了可调谐集成陷波带滤波器。在通带内观察到0.08 ns的群延迟。通过设计算例进行了实验，并对测量和仿真结果进行了比较。过滤器的物理体积为1.5 mm × 1.8 mm × 1.5 mm。
