What does terminate a signal pin with 50 ohm mean?

[EE-2002]

Hi ,

What does terminate a signal pin with 50 ohm mean? Does it mean tying the pin to GND through a 50 ohm resistor?

thanks for taking the time to respond.

Yes, in principle what you say is ok.
In general 50 ohms is referring to a load which is pure resistive.

hi EE-2002,

most RF circuits are designed to match at 50 ohm. So when you terminate a signal line with 50 ohm load, you are making the end of the signal line matched. Thus when there is a signal reaching the end of the line, it will get absorbed and not reflected back to the input.
