Things To Know 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.

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.

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.

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.

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 crucial that one will consider the various techniques that can often be utilized towards the implementation of these devices. You have to remember that there are techniques such as the lumped and feeder, coaxial, discreet elements, as well as stripline. They may even be contained in several packages as well.
