Hello,
I am looking for a tutorial to make a directional coupler in order to capture the power emitted and the SWR of an 88-108MHz FM transmitter up to a maximum power of 30watts.

Hello folkeu,

look for "Minicircuits TDC Directional Couplers".

They can do only 10 W Sad, but perhaps they have some
higher powered devices.
I successfully used the TDC-10-1 and TDC-10-2 for measuerments
with my spectrum analyzer.

The ARRL handbook/ARRL antenna handbook also have some suggestions.


Best Regards

This construction is so simple.

You can see all of the details at "Frequency independent directional wattmeter and swr meter" article
