Working with RF systems, sometimes it doesn't need to be too complicated, just a splitter with the right parameters, a directional splitter that does the right job, is enough to ensure the signal goes the right way and the measurement data is not distorted. But because they are so basic, many people easily choose the wrong one. Hybrid coupler and directional coupler are two devices that are often misunderstood, although each type serves a very different purpose.
