顾名思义，晶体管常用作混频器，可以输出混频信号，并且是许多电子通讯系统的基本元件。
As the name suggests, mixers produce output signals with mixed frequencies and are fundamental components of many electronic communications systems.
在第二部分，我们将着眼于活性成分，如射频晶体管，混频器，调制器和放大器，用于下一代无线电台。
In Part 2, we will look at active components such as RF transistors, mixers, modulators, and amplifiers for next-generation radios.
