Examples of 'directional couplers' in a sentence
Meaning of "directional couplers"
directional couplers: Directional couplers are electronic devices used in telecommunications and RF (radio frequency) systems to couple power from one transmission line to another. They are specifically designed to allow power to flow in one direction while blocking or attenuating power in the opposite direction
