摘要

A novel differential narrow-band band-pass filter design method is presented based on the parallel coupled line and the open stub. Based on the transmission line model, the proposed differential band-pass filter is analyzed by using even- and odd-mode analytical method. The central resonant frequency of the proposed differential filter is given. The relations between the filtering performance and the impedance parameters are discussed. A compact differential band-pass filter is designed based on the resonant conditions. The common mode signal is well suppressed. The differential band-pass filter is simulated, fabricated and measured. The measured results and the simulated results are basically consistent.
