看到几段话,不明白他们有什么区别,都是功率放大器的意思吗?
Avoid TX output (PPA, PA) disturbing DCO domain.
The transmit traces between Transceive and PA is recommended to be routed in inner layer.

PA是RF的功率放大器, PPA是TI DRP里面的预放大器(Pre-power Amplifier).
整句话的意思是防止发射部分(PPA,PA)干扰到DCO(数控振荡器)的区域, Transceiver和PA之间的线要走在内层
明白了,多谢cylbailey的解答!
