Applications of attenuators.

Explanation:

Attenuator Applications

There are so manyattenuator applications that we can observe in our daily life and a few of them are listed below:

1.Microwave power can be controlled using PIN diode attenuators, PIN diode is used as control element in most of the electronically variable attenuators.

2.To control volume of electronic equipment such as speakers, electric guitars, etc. attenuators are used.

3.In general, while conducting tests in laboratories only a small voltage or current signal is used for which attenuators are widely used to reduce output signal strength.

4.To test high power radio frequency signals, before applying it to the test equipment you should reduce the strength of the signal for which attenuators can be used.

5.While driving match sensitive radio frequency mixers it is really important to ensure that proper impedance match is obtained as poor match can lead to degraded performance. So, impedance matched radio frequency attenuator can be used to improve this matching and improve performance.

6.In some digital or analog circuits, a surge in voltage may cause damage to the circuits which can be avoided using attenuators to reduce high voltages.

7.In fibre optic communication, it is important to obtain proper match for transmitter and receiver which can be obtained using optical attenuators.

8.Basic signal generators will be able to generate an exact fixed level and to use this output signal we must use switch attenuators to reduce its signal which is less effective method compared to using a variable level control radio frequency attenuator that can be used to generate required levels.
