RF Directional Coupler

A directional coupler is a type of three-port RF (radio-frequency) device used to measure the amount of power flowing in a signal path. It is also used to couple power from one path to another, or to split the power between two paths. An RF directional coupler is a device that divides an incoming signal into two components, with one component travelling out the main port and the other travelling out the coupled port. The primary purpose of an RF directional coupler is to measure the input power, which is accomplished by monitoring the signal at the coupled port. This technique is known as RF power measurement, and it is used in a variety of applications, including radio transmitters, antenna systems, and RF signal testing.
