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.

These items are also referred to as power dividers or power splitters. If they're used while they are functioning in reverse, they are referred to as power combiners. They are passive devices that are often present in many of the appreciations that are involved with radio technology, they are most used towards coupling a defined amount of certain electromagnetic power that will be present on a specific 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 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 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.
