Specification tips; Define the package or Connector style, Power absorption, and VSWR.
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, in this context, is not a passive component but an active device using FETs and diodes. Step attenuators also also sub-divided into the number of steps they offer; switch positions on a rotary device, or switch positions on a device using toggle switches.

The style of RF Connector needs to be specified as it could be any of a number of types. Although the actual type might be determined by the frequency range of the attenuator. Also refer to the list of Companies making RF Connectors.
Additional RF Component Manufacturers, by type and vendor.

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.
