hey guys,

I am currently dealing with sinusoidal signals ranging between 200k and 30MHz and have to measure a phase difference of a few millidegrees between the two signals. I have read up on a few stratergies like using a PLL or IQ demodulation, but since we are working with such high frequencies it is best to obtain advice from experts here. thanks very much.

Best wishes
Joel
 

Try analog phase frequency detector.

It works well for sine waves.

You can search Gilbert cell PFD for your purpose.

thanks
