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.

It is not enough that you are knowledgeable of the process that will be involved here. It's important that aside from extensive technological knowledge, you are well aware of what it is that you need to use to come up with outputs that you are gunning for. Since you will need to have an appropriate device to let power pass through, the use of directional couplers may be something that you are going to need.

Do not start working on the project unless you've determined what it is that you're supposed to d or what tools you need to get. Before you head out to the store an gather what you need, it is important to list down everything. You can avoid having to end up missing on some of the stuff you require if you will see to to that you have listed down everything that you'll need.

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.

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 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 is important to consider the fact that there are several techniques that can be used towards implementing these couplers. There is the coaxial, the stripline, the lumped and feeder, as well as discreet elements. In addition, they may also be used to contain several varieties or packages.
