摘要
本教学用的散件为3V低压全硅管六管超外差式收音机,具有安装调试方便、工作稳定、声音洪亮、耗电省等优点。它由输入回路高放混频级、一级中放、二级中放、前置低放兼检波级、低放级和功放级等部分组成,接收频率范围为535千赫-1605千赫的中波段。本电路的设计和元件参数的选择都经过无线电专业工程师鉴定认可,在散件的组装组装过程中除可进一步学****电子技术外,还可以掌握电子安装工艺了解测量和调试技术,一举多得。
This teaching for 3 v low voltage with the bulk of the silicon pipe six superheterodyne receiver, with convenient installation and debugging, stable work, loud noise, power saving, etc. Put it by the input circuit high mixing level, level 1, level 2 put, low lead and detection level, low level and power amplifier level parts, such as receiving frequency range for medium frequency of 535 KHZ to 1605 KHZ. The circuit design and the selection of element parameters are identified, radio professional engineers in the
