摘要
该文首先详细分析了由 PTN 二极管构成的桥式双极电调衰减器的工作原理,并给出了衰减量与控制电流的关系式。然后,导出了在满足匹配,线性压控条件下的最佳驱动曲线。最后,给出了用于短波、超短波时的失真、匹配及分布参数影响等具体问题的设计考虑。
The principle of a bipolar bridge electronic attenuator composed of PIN diodes is firstanalyzed in detail.The relationship between attenuation and control current is given.Thenthe optimal driving curve under the conditions of matching and linear voltage control is de-rived.Finally,the result of analysis of the attenuator is given on problems of distortion,matching and effects of the hybrid parameters which should be taken into account whenthe attenuator is used in the frequency band of short waves.
