基于高功率开关的新兴发展，使用开关短截线的可调谐匹配网络在高功率雷达和干扰应用中显示出实时阻抗匹配的前景。这些自调谐发射放大器将在动态变化的频谱环境中改变工作频率时快速扩大范围。在本文中，我们提出了一种快速调谐算法，能够最大化具有六个开关短截线的调谐器的输出功率。演示了软件定义无线电平台对调谐器的控制，并且在工作频率或天线阻抗发生变化后，可以在 35 \ \mu\mathrm{s}$ 下执行输出功率的完整优化。该算法预计适用于具有相似重配置时间的新兴高功率开关。
Tunable matching networks using switched stubs show promise for real-time impedance matching in high-power radar and jamming applications based on the emerging developments of high-power switches. These self-tuning transmitter amplifiers will quickly maximize range upon changing operating frequency in a dynamically changing spectrum environment. In this paper, we present a fast tuning algorithm capable of maximizing the output power from a tuner with six switched stubs. The control of the tuner from a software-defined radio platform is demonstrated, and complete optimization for output power can be performed in under $35 \ \mu\mathrm{s}$ following a change in operating frequency or antenna impedance. The algorithm is expected to be applicable to emerging high-power switches with similar reconfiguration times.
