698-3800MHz N Female Directional Coupler

Directional couplers are a passive device used mostly in the field of radio technology. They couple a defined amount of the electromagnetic power in a transmission line to a port enabling the signal to be used in another radio system or next radio equipment. An essential feature of directional couplers is that they only couple power flowing in one direction. Power entering the output port is coupled to the isolated port but not to the coupled port. A directional coupler designed to split power equally between two ports is called a hybrid coupler, for example ,3dB hybrid coupler.

Vinncom directional coupler are based on different design ,such as micro-stripline,air-dielectric ,thin film ,waveguide etc.

Directional couplers have many applications. These include providing a signal sample for measurement or monitoring, feedback, combining feeds to and from antennas, providing signal taps for cable and/or Distributed Antenna Systems such as cable TV,mobile signal coverage and separating transmitted and received signals on telecom systems.
