Abstract :
A novel two-order bandpass filter (BPF) is proposed. The parallel coupling paths as well as similar zero point generation mechanism for the fundamental frequency and the first spurious frequency give the filter three controllable finite zero points in the stopband without adding any extra elements. Good skirt selectivity and controllable stopband characteristics can be achieved simultaneously.
