Abstract

This paper presents the method for analysis of diode frequency converters in the basis of nodal voltages employing the generalized matrix form in the frequency domain. Theoretical expressions for the transfer function of three (balanced, double-balanced and triple-balanced) circuits of diode frequency converters were obtained based on the specified method. Expressions for estimating the maximum attainable values of the transfer function were presented. The relationships of the mixer transfer ratios as a function of the load resistance and heterodyne voltage amplitude were also obtained. It has been shown that the variation of values of the load resistance and heterodyne voltage amplitude makes it possible to maximize the mixer transfer function. The presented results of simulating three circuits of diode frequency converters confirm the high accuracy of calculations. The possible error does not exceed 3 dB. The results of calculations and simulation are presented for two operating modes: heterodyne harmonic signal (non-intensive mode) and heterodyne pulse signal (intensive mode).

在频域中使用广义矩阵形式的节点电压法分析二极管混频器。第 1 部分：传递函数

摘要

本文介绍了基于节点电压的二极管变频器分析方法，该方法采用频域中的广义矩阵形式。根据规定的方法，得到了二极管变频器的三个（平衡、双平衡和三平衡）电路的传递函数的理论表达式。给出了用于估计传递函数的最大可达到值的表达式。还获得了作为负载电阻和外差电压幅度函数的混频器传输比的关系。已经表明，负载电阻和外差电压幅度值的变化可以使混频器传递函数最大化。对三个二极管变频器电路的仿真结果证实了计算的高精度。可能的误差不超过 3 dB。计算和仿真结果针对两种工作模式给出：外差谐波信号（非密集模式）和外差脉冲信号（密集模式）。
