Some Facts About Directional Couplers

By Jana Serrano


You have always been interested in radio technology, you know that there are a lot of technical aspects involved in these kinds of projects, but you are interested to learn what these are nevertheless. Making homemade projects that are going to use and harness the technology involved here is going to be fund and educational at the same time. So, you are determined to succeed in carrying out such an undertaking.

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.

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.

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 is important to understand that specifics of the device before you'll decide to start using them. For instance, one very essential feature that these power splitters have is that they're only able to couple those powers that are flowing towards a single direction only. This means that power entering the output port will only be coupled towards the isolated port. It is not coupled to the coupled port.

These kinds of devices are often constructed from two transmission lines that are coupled and set close enough together. They are coupled in such a way that the energy that will be passing through one is going to be coupled towards the other. Techniques like these are actually favored when it comes to microwave frequencies. The reason for this is because their transmission liens are designed to implement several circuits.

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.
