推挽式是一种有张力拉伸的环状结构。
现在，你可能会想，怎么能推挽放大器是A类？
Now, you might be thinking, how can a push-pull amplifier be class A?
您可以，确实有一个真正的A级放大器，工作在推挽模式。
You can, indeed have a true class a amplifier that operates in push-pull mode.
利用该结构，能够在电光调制器中实现完全对称的推挽操作。
With this structure, full symmetric push pull operation can be realized in modulator.
