A coupler is an incredibly useful building block in RF electronics. I’ll explain the basic theory behind it and demonstrate how to design and simulate such a circuit. Additionally, I’ll guide you through creating the RF PCB layout and share the measurement results using a NanoVNA. The results are impressive, especially considering that I’m using standard FR4 material and a very simple design process which does not require expensive EM simulators like HFSS or Microwave Studio.
