Rf Attenuators

RF attenuators are used to reduce signals, which is actually a very valuable attribute when it comes to RF systems. Just as lack of signal strength can present problems, so too can an overabundance of signal gain. RF attenuators can make a previously unusable signal into a valuable data stream.

When using attenuators, RF professionals act much as Hollywood editors might. Movie directors film many more hours of footage than can be used in a feature-length film. An editor's job is to take the many reels of film and condense them into a two-hour long product. While most of the film is left on the cutting-room floor, every bit of film is essential to the movie nonetheless. Without all of the footage, there would be far fewer choices to be made; more options lead to a superior final cut.

Those sending RF transmissions use similar guidelines. We all know that too weak a signal will lead to an inferior transfer of data. Better to use to strong a signal, and then tone it down once it reaches its destination. Such a process ensures accurate and complete transmissions.

The Role of RF Attenuators

Of course, in order to use such powerful transmissions, one needs some method of conversion. RF attenuators reduce transmission strength by a certain amount. The amount by which the transmission is reduced is dependant on the system for which the signal is intended.
