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.

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 devices are commonly used in radio technology. Often referred to as the power splitters, they are passive units that are used on many of the applications that are carried out in radio technology. They're often defined based on the amounts of electromagnetic power in a certain transmission line towards a port. This will then enable the signal that can be used for another circuit.

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 different applications that the devices can be sued for. For instance, they can be used to provide a signal sample towards the monitoring or the measurement of the cable distributed system like TV. It can be used towards combining feeds to an antenna and from it, they can also help in the beam forming of antenna, as well as provide taps for the same system. They can be used for separating the transmitted and received signal 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.
