| Abstract: | Narrow-band filters and multiplexers based on metal cavities have been widely used in communications, radar, satellite, and aerospace due to their low insertion loss, high quality factor, and high power capacity. Compared with single-mode resonators, multi-mode resonators can significantly reduce the size, weight, and cost of circuits, and effectively increase frequency selectivity. This article outlines the development of microwave cavity filters and multiplexers, including narrow-band, wide-band, and multi-band filters, and duplexers, multiplexers, and three-state duplexers. |
