Things To Learn About Directional Couplers

By Jana Serrano


Radio technology has always been something that you have an interest with, you like to tinker stuff and this is something that have immensely caught your interest along the way. This may involve a lot of technical mumbo-jumbo though, but this is something that you have always find interesting. Of course, you want to see if there is a way for you to start using the things you have learned so far to come up with something.

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.

Try not to start on the project unless you have gathered everything that you'll need. It is always best that you will determine everything that you'll likely require for this work to get started before you do start things. It is easier to visit the store and gather the stuff that you require when you have listed everything down. This prevents those instances when you might actually end up forgetting something.

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.

Make sure that you have an idea of the actual uses of these devices before you will decide to sort through and use it for the purposes that you will require. It is important that you have to take into consideration how they are only able to couple power that will be flowing towards one direction only. Hence it is going to be coupled to the isolated port but not to the port that it is coupled with.

Most of the time, these types of splitters are constructed with the use of two transmission lines. They are coupled and then set close together. This is done so that the energy that is passing through one is expected pass through one that will be coupled to the other. Most using this technique prefer to favor this when doing microwave frequencies due to the presence of the many circuit elements.

There are several applications that these devices can then be used for. In the cable TV systems, they can be used in providing taps, antenna beam forming, combining the feeds from and to an antenna, providing feedback, as well as providing a signal sample for measurement and monitoring. In addition, they are very helpful towards separating the received and transmitted signals in 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.
