摘要：

A wideband filtering impedance transformer (WFIT) based on transversal interaction concept is presented. The proposed WFIT has four reflection zeros in the passband to broaden the operating bandwidth. Moreover, two transmission zeros are generated to enhance the selectivity. For verification, a prototype is designed, simulated and measured. The measured results show that the proposed WFIT has about 60% bandwidth in terms of S-11 larger than 20 dB and the rejection out-of-band is better than 30 dB.
