本文提出了一种计算机控制的变容管宽带电调谐电路线性化处理的方法。它的原理是,通过简单的交换可以从非线性调谐特性数据得到线性化所需要的补偿特性数据,然后利用成功失败搜索DFP优化算法,用一个多项式对它拟合。目标函数是根据加权最小二乘法建立的。所得到的多项式系数可放在计算机ROM中,以实现线性化的频率控制。 This paper presents a computer-controlled varactor wide band tuning circuit linearization method. The principle is that the compensation characteristic data needed for linearization can be obtained from the nonlinear tuning characteristic data by a simple exchange, and then the DFP optimization algorithm is searched using a successful failure, and it is fitted with a polynomial. The objective function is based on a weighted least squares method. The resulting polynomial coefficients can be placed in computer ROM to achieve linear frequency control.
