Passive Attenuators
A Passive Attenuator is a special type of electrical or electronic bidirectional circuit made up of entirely resistive elements.
An attenuator is a two port resistive network designed to weaken or “attenuate” (hence their name) the power being supplied by a source to a level that is suitable for the connected load.
It reduces the amount of power being delivered to the connected load by either a single fixed amount, a variable amount or in a series of known switchable steps.
These are generally used in radio, communication and transmission line applications to weaken a stronger signal.
It is a purely passive resistive network (hence no supply) which is used in a wide variety of electronic equipment for extending the dynamic range of measuring equipment by adjusting signal levels, to provide impedance matching of oscillators or amplifiers to reduce the effects of improper input/output terminations, or to simply provide isolation between difference
