一、前言对数中频放大器从理论计算到研制已由有关学者和工程技术人员进行过长时间的探讨与实践,然而迄今为止,仍然存在以下一些问题: 第一,理论计算值与实际值相差甚远。第二,高指标对数中放的研制仍然相当困难,周期很长。经过实践,我们已很好地解决了上述问题。本文将着重于介绍一种新的结构装配形式及实际调整方法,给出计算途径。二、主要参数及其计算值当给定主要参数值中心 I. Introduction The logarithmic IF amplifier has been discussed and practiced by scholars and engineers for a long time from the theoretical calculation to the research and development. However, there are still some problems so far. First, the difference between the calculated theoretical value and the actual value far. Second, the development of high-index logarithmic release is still quite difficult and the cycle is very long. After practice, we have solved the above problems. This article will focus on the introduction of a new form of structural assembly and practical adjustment methods, given the calculation approach. Second, the main parameters and their calculated value When given the main parameter value center
