Customised 500MHz-40GHz directional couplers (no custom quantities required, one piece minimum, quality assurance, affordable prices)
product description
Directional coupler is a four-port network widely used in microwave systems with directional power coupling (distribution) elements.The coupling principle of directional coupler is mainly divided into small-hole coupling, parallel coupling, branching coupling, and matched double-T. Directional couplers can be composed of a variety of transmission lines, such as coaxial lines, rectangular waveguides, circular waveguides, strip lines and microstrip lines, and so on, so there is a wide variety.
