摘要

本文提出了一种以螺旋阻抗轨迹作为频率响应的无源网络。松耦合传输线产生风车轨迹，而长传输线使轨迹绕参考阻抗原点多圈旋转。这使得系统的输出阻抗能够在史密斯图上覆盖很宽的范围。该方案在射频功率系统激励未知或时变负载时的频分集阻抗匹配中非常有用。

Diskwide Spiral Trajectory Impedance Matching Network for Frequency-Diversity Power Transfer

This paper proposes a passive network that exhibits a spiral impedance trajectory as its frequency response. A loose-coupled transmission line generates a pinwheel locus, while another long transmission line makes the locus revolve in multiple turns around the reference impedance origin. This enables the system's output impedance to cover a wide range on the Smith Chart. This scheme is considerably useful in frequency-diversity impedance matching for RF power systems to excite an unknown or time-varying load.
