Basics of RF Directional Couplers in Various Applications

Directional couplers are typically utilized in RF design applications. Directional couplers, which are passive devices, are utilized to couple a certain proportion of power that travels in one transmission line and out through another connection. Directional couplers are used for a variety of applications in RF design, including transmitter automatic levels controls and through-line power sensors. They are highly useful, and are capable of allowing power levels to be sensed in
