DIRECTIONAL COUPLERS
DETI offers a large range of RF and microwave couplers from 6 up to 50 dB coupling factor, covering selected frequency bands up to 27 GHz.
DETI designs different types of couplers :
Compact and performant, DETI’s directional couplers are low-loss with accurate coupling. Their high directivity guarantees a good isolation between different ports.
They are designed to operate in severe environment and respond to various applications. We use stripline for standard wide-band coupler and airline technology when power increase. If couplers of our catalog do not match with your request, please contact us we can work on specific product.

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.
