摘要
基于金属腔体的窄带滤波器和多工器因其低插入损耗、高品质因数和高功率容量等优势已被广泛应用于通信、雷达、卫星和航空航天等领域。与单模谐振器相比,多模谐振器可以显著地减小电路的体积、重量,降低成本,并有效地提高频率选择性。文章概述了微波腔体滤波器与多工器的发展概况,包括窄带、宽带和多频带滤波器,双工器多工器,三状态双工器等组件。
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.
