Abstract: This ppt presents the design and implementation of a class of multiple-mode wideband bandpass filter (MMRBPF). This BPF consists of a single waveguide cavity which is used to design triple-mode, quadruple-mode and quintuplet-mode wideband filter. This technology also extend to design a triple-mode dielectric filter and diplexer. The widest fractional bandwidth is equal to 360% at center frequency of 3.2 GHz, and the insertion loss is less than 0.5 dB in center frequency. The high performance BPF provides an alternative approach to develop a cavity-type of wideband filter for miniaturized base-station communication.
