本文所讨论的双态电抗性移相开关。其特点是相移随频率的变化极小。而相移量则可通过调节电抗性负载(电容或电感)的大小获得。电路形式比较简单,特别是当所使用的PIN管是微带型时,则所有电路均可设计在一个导体平面内,给印制和调整带来了方便。 The two-state reactive phase-shift switch discussed in this article. It is characterized by minimal phase shift with frequency. The amount of phase shift can be obtained by adjusting the size of the reactive load (capacitance or inductance). The circuit form is relatively simple, especially when the PIN tube used is a microstrip type, all the circuits can be designed in one conductor plane, which brings convenience to printing and adjustment.
