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.

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.

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.

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 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.
