摘　　要：目前,甲、丙类调谐放大器的理论研究较为离散,缺少多级级联系统设计的理论分析与测试方法。根据设计案例指标需求,结合理论分析,采用Multisim进行仿真与测试,对级联系统设计中元件参数测量、电路参数计算、系统稳定性调整、工作状态调整、效率计算、阻抗匹配等关键问题进行了详细解析。仿真实验表明设计符合指标要求,可作为甲、丙类多级级联调谐放大器系统设计的参考。At present, theoretical research on class A, C tuned amplifier is discrete, especially lacking of theo- retical analysis and test method for cascaded system. According tothe indexes of a design case, combining theo- retical analysis with simulation and test by Multisim, some key issues in cascaded system design are detailed, including measurement of component parameters, calculation of circuit parameters, system stability regulation, working condition adjustment, efficiency calculation, impedance matching. Simulation results indicate that the design method achieves the technical requirements and can be a reference for systematic design of class A, C cascaded tuned amplifier.
