RF Coupler Basics & Selection
The directional coupler is a kind of microwave device widely used in microwave systems. Its essence is to distribute the power of the microwave signal according to a certain ratio.
Directional converters are composed of transmission lines. Coaxial lines, rectangular waveguides, circular waveguides, strip lines and microstrip lines can all constitute directional converters. Therefore, there are many types of directional converters from the structural point of view, and there are great differences. But from the perspective of its conversion mechanism, it is mainly divided into different ones, namely small hole supplement, parallel supplement, branch replacement and matching double T.
A directional coupler is an element that places two transmission lines close enough and where the power of one line can be exchanged to the other line. The signal amplitudes of its two output ports can be changed or unequal. A particularly widely used supplementer is a 3dB supplementer. The amplitudes of the output signals of the two output ports of this supplementer are similar.
