RF

Hi,

I am trying to put together a wireless system fo the first time. I was told to use a wireless chip nRF24z1 for both transmitter and receiver. I need to layout the PCB for this chip first. So, I found the following note

But I can not understand the following issue

The note says that all layouts should be fitted with a single ended connection to a 50ohm antenna by using a differential to single ended matching network. What does it exctly mean?

Thanks John
