Things To Know 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 like these have to be done in such a way where you have extensive knowledge of the actual process. You cannot expect to do a fine job of doing the task when you lack the technical know-how on the way the output you are aiming for should be created. Then, you need tools and resources. Along them, you need directional couplers to ensure that power gets to pass through the device when turned on.

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.

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 is crucial that one will consider the various techniques that can often be utilized towards the implementation of these devices. You have to remember that there are techniques such as the lumped and feeder, coaxial, discreet elements, as well as stripline. They may even be contained in several packages as well.
