Dual directional crossguide couplers belonging to a type of waveguide cross coupler, it has the particularity of dual directionality.

A waveguide cross coupler typically consists of two coplanar waveguides perpendicular to each other. When an electromagnetic wave in one waveguide reaches and passes through a crossing point, it will be transmitted to another waveguide. In this process, because the intersection points between waveguides have a certain angle, a portion of the energy is transmitted to another waveguide, thereby achieving coupling. This transmission method can simultaneously transmit two orthogonal modes, so the waveguide cross coupler has a high degree of orthogonality.

Application:

The product is widely used in microwave measurement, sampling, high-power detection, microwave feeding systems, radar, communication, navigation, satellite communication and other systems.
In the field of communication, waveguide cross couplers can be used to extract microwave signals from one waveguide and couple them into another waveguide, achieving connections between different frequency bands. For example, in satellite communication systems, waveguide cross couplers can be used to couple the output ports of amplifiers at all levels, making signal transmission between levels more accurate and reliable. In addition, waveguide cross couplers can also be used to construct two-dimensional or three-dimensional network structures in optics.

Characteristics:

There are standard waveguide types such as rectangular, flat rectangular, medium flat rectangular, and double ridge, which have the characteristics of high directionality, low VSWR, low frequency response, and full wave conduction band width.

Qualwave supplies broadband and high power dual directional crossguide couplers in a wide range from 5.38GHz to 40GHz. The couplers are widely used in many applications.The basic materials for waveguide high directional couplers are copper and aluminum, with surface treatments such as silver plating, gold plating, nickel plating, passivation, and conductive oxidation. The external dimensions, flange, joint type, material, surface treatment, and electrical specifications of waveguide couplers can be customized according to user requirements.
