Attenuators are classified as either fixed or variable and either reflective or non-reflective for both waveguide and coaxial systems.
Fixed attenuators have fixed input and output impedances.
Variable attenuators can be subdivided into two kinds: step attenuator and continuously variable attenuator. A variable attenuator, n this context, is not a passive component but an active device using FETs and diodes.
A reflective attenuator reflects some portion of the input power back to the driving source. The amount reflected is a function of the attenuation level.
