摘要
在介绍调谐放大器的基本概念、结构和用途的基础上,重点研究其频率特性,利用MATLAB推导出其通频带宽度的计算公式,并利用MULTISIM对该计算公式进行了仿真验证,然后分析了部分接入式调谐放大器的优点,得出其带宽计算公式,最后举例说明了该公式在实际调谐放大器设计中的应用。
Based on the illustration of tuned amplifiers＇ fundamental concepts,structures and application,this paper focus on its frequency characteristic. Besides,the formula,to calculate its circuit frequency bandwidth,has been derived by MATLAB and verified by MULTISIM. Then it analyzes the advantages of partial access tuned amplifier,derives its bandwidth formulas,and finally illustrates the practical application of the formula in tuned amplifier design.
