摘要
研究了高频小信号单调谐放大器实验,采用扫频法和点测法分别测量幅频特性曲线,观察了集电极负载对幅频特性的影响,计算了放大倍数并观察其动态范围,在实验中测试各组数据,验证并巩固了调谐放大器电压增益、通频带、选择性等相关知识和计算方法。为进一步掌握高频小信号调谐放大器的工作原理奠定了基础。
The research designs the experiment of high frequency small signal single tuned amplifier, which uses frequency-sweep method and point measuring method to measure amplitude-frequency curve, observe the influence of the collector load on the amplitude-frequency characteristic, calculate the magnification and observe its dynamic range. The test data in the experiment verify and consolidate the relevant knowledge and calculation method of tuned amplifier voltage gain, passband, selective. The research lays a foundation for further grasp the working principle of high frequency small signal tuned amplifier.
