“调屏调栅振荡电路”是一种基于电子管(真空管)结构的振荡电路,主要用于早期无线电设备中。其名称来源于电路中对电子管的屏极(阳极)和栅极进行调谐的设计。以下为详细解释:
核心元件
电路由电子管、调谐电感(L)和调谐电容(C)组成。
工作原理
电子管作为放大器,将直流电能转换为交流信号。通过屏极和栅极的LC调谐网络形成正反馈,满足振荡条件(相位一致且增益≥1),从而产生持续振荡。
频率调节
通过调整屏极或栅极的电容/电感值,可灵活改变输出信号的频率,适用于需要频率可调的场合(如早期无线电发射机)。
典型应用场景
振荡频率由屏极和栅极的LC参数共同决定,公式为:
$$
f = frac{1}{2pi sqrt{L{text{屏}}C{text{屏}} + L{text{栅}}C{text{栅}}}}
$$
(注:具体公式可能因电路设计差异而调整,需参考实际电路图。)
