I made a 2.4g power standing-wave meter with the power detection part cut from pa.The calibration seems to work fine.But I don't know if it's correct to use a looper for this kind of detection.

Is this circulator really 1500-1700MHz?
Then it won't work on 2,4GHz properly.

Aha, you set a "trap"..
BTW, this ring device is called "circulator"

Florian, Zhao Feng uses Google translate, so sometimes 'approximate' words come up, but we get the point : -)

In a round about way. I think you are doing it OK, but you can tell by calibrating it with your test gear. If it works correctly into a load then it will probably work into the antenna because of the presence of the circulator. This means your coupler does not need to be directional, it just needs to measure the voltage or current. Any reflections which would make this measurement inaccurate are prevented by the circulator.

I ordered several different frequency circulator.A very low price...
