The real part of impedance of matching network is represented approximately by a number of straight line segments on logarithm coordinate so that greatly simplifies the calculation of phase function and reduces the degree of nonlinearity of transduce power gain .

该方法将匹配网络输入阻抗的实部近似用对数坐标中的若干直线段表示，简化了相位函数的计算，降低了功率 增益 传输函数的非线性。
