RF Variable Attenuators - Everything RF
More about RF Variable Attenuators. Variable attenuators, like the name suggests are attenuators whose attenuation amplitude can be changed by varying the voltage or current to the device. These are used in application where it is required to continuously vary the signal level. Key Specifications: ... Doc Retrieval

Attenuator (electronics) - Wikipedia
An attenuator is an electronic device that reduces the power of a signal without appreciably distorting its waveform.. An attenuator is effectively the opposite of an amplifier, though the two work by different methods.While an amplifier provides gain, an attenuator provides loss, or gain less than 1. ...
