Some Facts About Directional Couplers

By Jana Serrano


You've since been interested in technical stuff. You have since been tinkering items every now and then and you would want to find ways on how you can improve your knowledge in the field. This is especially true when it comes to radio technology. With the available technology there is these days, you know that it is more than possible for you to successfully make something on your own.

Projects of this kind always have to rely on your knowledge on how they are supposed to work. They would require the right tools that you can use too. Then, there are resources that are needed to be attached to whatever device it is that you are making to ensure that there is proper power flow when it is turned on. A very important part that you would utilize for such purposes would be directional couplers.

Remember that for projects kike these to really get done right, having the right tools would be important. Before you go to the stores and shop for the stuff that you need, it pays to actually take not of a number of things that you need first, this allows you to check things ahead of time and ensure that at the end of the day, you will never end up forgetting some of the things that you require.

The items are often referred to as power splitters or power dividers. In the event that they are used in reverse they are considered as power combiners. These passive devices are often use in many applications that are involved in radio technology. They make it possible for signals to be used on a different circuit with the coupling of a specific amount of electromagnetic power that is present in a transmission line.

It's important to understand how these devices are supposed to work before you'll decide to start utilizing them for your applications. For instance, an essential feature that you have to take into account when using these splitters is that they can only couple a specific amount of power in a single direction. Hence, the power that will enter the output port is coupled towards the isolated port, but not towards the coupled port.

Devices like these are usually constructed from two transmission lines which are then coupled enough together. They are set close enough so make sure that the energy will be passing through one is coupled with the other. Most would favor these with microwave frequencies since their transmission line designs tend to implement many circuit elements.

There are a number of applications that these devices can be used for. In systems like the cable TV, they can be used towards providing taps, feedback, providing the signal sample for the monitoring and measurement, and the forming of antenna beam. Also, they are used towards separation that signal that are transmitted and received on the telephone lines.

It's important to note that there are various techniques that can also be used to implement these splitters. For instance, one can utilize the them as coaxial, stripline, discreet, or feeder and lumped elements. They may also have a variety of packages from solder pins, blocks from RF connectors, and they may even be contained on certain substrate carriers.
