Description
RF Directional Coupler
RF Directional Coupler using PCB as coupling.
Bottom layer is just a ground plane.
The design is then verified with Rigol DSA. At 2m band, the response is quite flat at -30 dBm.
On HF, the response is acceptable flat and a graph can be used to aproximate the coupling factor.
I use this couple to measure RF spectrum output from Amateur Radio transceiver.
