在变容管的各种参量应用中,变容管的非线性性能成为最基本的重要资料。提高变容管的非线性度,在应用中可以相应减小注入功率。在研究低注入或其他非正弦波注入应用的特性时,更应对变容管时变参量的基波及谐波分量与变容管非线性度及注入电压比等之间的关系深入研究。本文目的在于分析上述问题,选用合适的非线性性能的表示法,采用图解法求出变容管归一化时变参量的基波及谐波分量的特性,并绘出这些分量与变容管非线性度γ,注入电压比m_1之间的关系曲线。这些通用曲线在分析变容管的各种参量应用中可作为重要参考资料,并举例示出这些曲线的用途。
Varactor in a variety of parameters of the application, the varactor nonlinear properties become the most basic important information. Improve the non-linearity of the varactor in the application of a corresponding reduction in injection power. When studying the characteristics of low injection or other non-sinusoidal injection applications, more in-depth study of the relationship between the fundamental and harmonic components of the varactor time-varying variable and the varactor nonlinearity and injection voltage ratio. The purpose of this paper is to analyze the above problems, select the appropriate representation of nonlinear properties, using graphical method to find the time-varying parameters of the varactor normalized fundamental and harmonic components of the characteristics and draw these components and varactor tube Linearity γ, injection voltage ratio m_1 between the relationship curve. These general curves serve as important references in the analysis of various parameters of varactors and illustrate the use of these curves.
