Combiners

Combiners are great tools for improving the quality of RF transmissions. You've heard, I assume, the phrase, "Two heads are better than one." Well, in the case of RF systems, two signals can be better than one!

Combiners make this meeting of the minds (or signals, in this case) possible. These devices are used to put together two signals that are carrying the same data. The resultant stream is quite a lot better than either of the original streams, leading to a more complete and usable transmission. As you can see, the power of teamwork extends even into the RF realm.

Combiners Team Up Signals

Of course, steps must be taken to make sure that the two signals can inhabit the same space without too much bickering. This is especially true of signals that are of different amplitudes. Feedback is great if it's constructive, but such noise is most always a detriment to RF systems. Everyone's contribution needs to be heard if a system is to function accurately.

The path to teamwork is found, ironically enough, through isolation. Isolation allows for each signal to come through loud and clear, without generating extraneous reflection. As strange as it may sound, signals are best able to work together when they are kept separate. Combiners with isolation capabilities make such dual efforts into one sterling success.
