PURPOSE:To improve the linearity of the modulation signal by inserting the parallel circuit of the diode and the resistance in series to the line which supplies the modulation signal. CONSTITUTION:The current-voltage characteristics of the diode in bridge-type modulator circuit 2 features the square...
实现double-balanced ring modulator 的另一种方法。 图4.实现 double-balanced ring modulator 的另一种方法。 两个电路都实现了相同的基本概念:将消息信号乘以在 ±1 之间切换的方波。正如上一篇文章中关于环形调制器的讨论,与二极管电桥调制器相比,这放宽了带通滤波器的过渡带要求,并使输出信号的幅度增加了一倍。

Diode Modulator. One of the simplest amplitude modulators is the diode modulator described in Sec. 4-1. The practical implementation shown in Fig. 4-7 consists of a resis-tive mixing network, a diode rectii er, and an LC tuned circuit. The carrier (Fig. 4-8b) is applied to one input...
