Radio Frequency Circuit Design

 
When you speak of electricity, the idea of radio frequency circuit designs is not widely known and understood. Why? Well, it is because one of the most prominent misconceptions that have been associated with the idea of electricity is how wires are considered to be the sole carriers of electrical energy from one location to another. From high-voltage transmission lines to printed circuit boards, wires appear to all there is to the world of electricity.

Well, the fact of the matter is that the world of electricity and electronics has transcended the stage of physical interconnections into the realm of wireless functionality. Radio frequency circuit designs are one of the several ways that are used by engineers for the purpose of enriching electrical systems with wireless functionality.

Radio frequency circuit designs are based upon the concept of electromagnetic radiation. Here are some of the reasons why electromagnetic radiation-based radio frequency circuit designs are favored over their alternatives for the purpose of making electrical systems wireless:
 

Speed

The primary reason why radio frequency circuit designs are preferred over their alternatives is how fast that transfer of signal can be through its usage. It is a fact that electromagnetic radiation serves to be a practical communication medium, regardless of what the frequency might be. What this means is that the speed of signal transfer will not significantly vary even if a high frequency signal is transferred, ultimately meaning that radio frequency circuit designs are able to achieve extremely high speeds of data transfer.
 

Range

One of the basic reasons for the pursuit of wireless communication lies in the greater goal of long-distance communication. If you think about it, extremely long distances in communication cannot be elapsed with electrical systems that involve wires, owing to their obvious limitation. Electromagnetic radiation, when used in conjunction with sophisticated recovery circuits and modulation techniques, can prove to be remarkable when it comes to the transfer of usable signals over long distances. As the distance increases, however, the strength of the radio frequency signal will continue to decrease, but the impact will not be as severe as in the case of the traditional alternatives.
 

Line of Sight

When it comes to speed and range, the only wireless communication medium that can match electromagnetic radiations is light. However, the fact that light requires a clear line of sight to be used as a communication medium, while electromagnetic radiations do not, tips the debate hugely in the favor of the latter. It is because our world is full of solid objects that can block even the most powerful sources of light. What this means is that the electromagnetic radiation will be able to transfer the signals through such objects which would serve to be nothing more than hindrances, had light been used.
 

Conclusion

When you take it all into perspective, you have got to say that that radio frequency circuit designs have played a major role in making the world of electronics wireless!
