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 of this kind always have to rely on your knowledge on how they are supposed to work. They would require the right tools that you can use too. Then, there are resources that are needed to be attached to whatever device it is that you are making to ensure that there is proper power flow when it is turned on. A very important part that you would utilize for such purposes would be directional couplers.

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 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'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 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's important to note that there are various techniques that can also be used to implement these splitters. For instance, one can utilize the them as coaxial, stripline, discreet, or feeder and lumped elements. They may also have a variety of packages from solder pins, blocks from RF connectors, and they may even be contained on certain substrate carriers.
