拼板机高频信号源的研制

拼板机高频信号源的第一级为信号发生电路,采用晶体振荡器作振荡元件,配以外围元件,产生的高频信号经信号放大电路及功率放大电路进行放大,可供功率输出电路作为信号源使用。经研究小组设计制作及多次测试,不断改进电路结构和参数,取得了良好的效果,并对功率输出电路做了初步设计。

The first stage of the high frequency signal source of the butt joint machine is the signal generating circuit, and the crystal oscillator is used with the peripheral components, and the high frequency signal is amplified by the signal amplifying circuit and the power amplifier circuit. Through the research group design and manufacture and many tests, the circuit structure and parameters of continuous improvement, achieved good resuhs, and the power output circuit to do a preliminary design.
