Redpitaya RF output power

Hello people,
I'm designing a power amplifier to use with my 125-14, and use it as a remote SDR for ham radio.
I need to know the output power of the OUT 1 and OUT 2, for design the PA's driver.
Anyone has this information? Where I can get it?

Thanks in advance,
Best Regards

Pedro

Hi,
you can expect a power level of 10mW (+ 10dBm). According to the technical data, it is ± 1V into a 50Ω load.
My measurements yielded between 6 and 10mW.

Hello Sigi!
Thank you very much for your reply, appreciated it!
First I will add a 3dB attenuator to the PA and see how it works, then I can remove it...
