论文摘要
本文推出了一种新技术，用于利用燃气管等离子体电池作为开关组件的高速，高功率移动形式因子调谐器。据我们所知，这代表了第一个支持等离子的RF匹配网络。审查了技术开发，提出了概念验证转换存根阻抗调谐器的制造和测量，并讨论了改进技术。概念验证阻抗调谐器的功能为27％的带宽从3到4 GHz，并且在所有开关状态频率组合中，功率增益优于-2.5 dB，其功率在50 W输入功率水平上具有50 w的输入功率，并具有史密斯图表的扩散覆盖率。状态变化瞬态时序测量为500 ns的顺序。该技术演示强调了微型化，快速可调，高功率，基于等离子体的RF设备的潜力。
This paper introduces a new technology for a high-speed, high-power mobile form-factor tuner utilizing gas discharge tube plasma cells as switching components. To the best of our knowledge, this represents the first plasma-enabled RF matching network. Technology development is reviewed, the fabrication and measurement of a proof-of-concept switched stub impedance tuner are presented, and techniques for improvement are discussed. The proof-of-concept impedance tuner functions with a 27% bandwidth from 3 to almost 4 GHz and shows a power gain better than -2.5 dB across all switching state-frequency combinations at a 50 W input power level with spread coverage of the Smith chart. State change transient timing is measured to be on the order of 500 ns. This technology demonstration highlights the potential of miniaturized, rapidly-tunable, high-power, plasma-based RF devices.
