Swr

Hi guys,
What is the standing wave ratio for LimeSDR USB type-A? Where could I find those specs? Please help. Thank you :slight_smile:

My guess is that the various ports are in the 50-70 Ohm range, making the SWR vary between 1:1 to 1.5:1.

Thank you :slight_smile: Do you know if there is official documentation that shows those spec?

I would guess that a QRP (Low Power) SWR meter would be needed. Along with different load resistances.

Presumably the LMS7002M chip datasheet has S1-parameter data for the different ports on the chip.

Usually when this type of question is asked, thereโ€™s some reason behind it.

Do you believe that the ports on the board are wildly-different from 50-80 ohms, perhaps only in
certain cases?
