什麼是功率放大器？What is a Power Amplifier?

功率放大器主要功能是將訊號放大後輸出, 使訊號能夠傳送到更遠的距離。

The primary function of a power amplifier is to amplify a signal and then output it, allowing the signal to be transmitted over a greater distance.

 

其主要分為The main types are：

√功率放大器 Power Amplifier (PA)

√低雜訊放大器 Low Noise Amplifier (LNA)
