How to Choose Best Attenuators?

Attenuators are electronic devices which reduce the amplitude or the power of a signal, without affecting the waveform much. Choosing the right attenuator is not an easy job and needs much time. It always depends upon the purpose for which it is needed.

 If you want to reduce the amplification of an electronic device it is best to choose power attenuators. These reduce the unwanted and loud noise produced by electronic devices like the electronic guitars.

If you want to do engineering and production tests in labs then a digital attenuator is the right choice for you. Even integration into high speed automatic-test-equipment systems or ATE systems will need a digital one.

Attenuators are also used in decreasing the strength of optical signals passing through the fibre optic cables or through the air. These are called optic attenuators.

 If your requirement includes dissipating powers, lowering the voltage along with improvement in impedance matching, then you should go for fixed attenuators.

There are various types of TNC attenuators. TNC attenuators have also find its way in telecommunication networks. These are used in scaling back the levels of the optical intensity which is necessary in maintaining the appropriate conditions. It is also used in equalization of the optical power between different wavelengths in fibre systems.

Choosing the perfect attenuator will depend on the following factors:
Input power
Operating frequency
Maximum loss in conversion
Operating temperature range

Other than these, attenuators are available for wireless communication, radio frequency, voltage variable, coaxial or coax, power, programmable, audio and many more. There are filters available in the online websites which will help you to get the right one for your requirements.
