A directional coupler is a 4-port passive device that is used to sample a portion of an input signal for test and/or monitoring purposes. This small amount of signal is measured at the coupled port and allows to obtain incident power, reflected power, VSWR values… It can be useful to evaluate the level of transmitted power in a component or part of RF chain, control signal received in an antenna etc. Uses and applications can determine one of the most important specification of directional coupler : the coupling factor. This is the difference between the input signal and the sample signal observed at the coupled port. DETI develops its devices with accuracy and offer knowledge to obtain the best specifications.
Depending of the application, RF and microwave directional coupler can be uni directional / bidirectional, dual directional or high power coupler. This different kind of coupler defines the technology used to realize the function.
