摘要

提出了一种测量铁电薄膜大信号介电常数和损耗正切的简便方法。在直流偏置为零的情况下，利用大信号介电特性建立了铁电变容管的可缩放大信号电路模型。该模型可用于铁电变容管的零偏混频器(上、下变换器)和谐波发生器的应用。

Large signal circuit model of parallel-plate ferroelectric varactors

A simple method is proposed to measure the large signal permittivity and loss tangent of ferroelectric films. Measured, at zero DC bias, large signal dielectric properfies are used to develop scaleable large signal circuit models of ferroelectric varactors. The model is useful for zero bias mixer (up and downconverter) and harmonic generator applications of ferroelectric varactors.
