在敌对环境中工作的雷达和通信系统必须频繁地抑制干扰或干扰机信号。许多抑制技术虽己被开发出来,但大多数使用缓慢,而且需要昂贵的硬件或要求窄带宽工作。一种使用非线性负载和定向耦合器的简单电路,能够快速抑制强干扰,并且可以使所需要的宽带信号通过。 Radar and communications systems that operate in hostile environments must suppress interference or jammer signals frequently. Although many suppression techniques have been developed, most are slow to use and require expensive hardware or require narrow bandwidth work. A simple circuit that uses non-linear loads and directional couplers to quickly suppress strong interference and to pass the desired broadband signal.
