摘要
军事通信的飞速发展加快了各种频段跳频电台的研制与应用,然而适应快速跳频的多路耦合器发展滞后,往往成为天线合路的技术瓶颈。该文以甚高频(VHF)跳频多工器为研究对象,采用宽边耦合带状线结构设计出适应30～88MHz频段的90°定向耦合器,结合电调滤波器实现了一种新型四路跳频多工器方案,并运用ADS电路仿真手段验证了该方案的可行性。
The fast development of military communication speeds up the study research and application of various frequency-hopping transmitter-receivers,but the corresponding multicoupler could not satisfy the new requirement,and becomes the bottle-neck of antenna-combining technology.Aiming at the VHF frequency-hopping multicoupler,a 90-degree directional coupler covering 30～88 MHz frequency range is designed by making use of wide edge coupled strip line,then a novel scheme of four-channel frequency hopping multicoupler composed of 90-degree directional couplers and electronically tunable filters is realized.The experiment by ADS circuit simulation proves the feasibility and practicability of this scheme.
