Abstract
To improve spurious characteristics of the dual-mode cavity resonator, the stepped cavity resonator is proposed, and the difference between the fundamental resonant and the spurious resonant frequencies is a 200 MHz improvement seen in the case of stepped cylindrical fundamental band of 1.8 GHz against the conventional cylindrical cavity. These are used in a two-stage BPF, showing an improvement in spurious characteristics.
