The attenuator has the following basic uses:

1) Control power level: Control the output power of the local oscillator in the microwave superheterodyne receiver to obtain the best noise figure and frequency conversion loss, and achieve the best reception effect. In the microwave receiver, realize automatic gain control and improve the dynamic range.

2) Decoupling element: As a decoupling element between the oscillator and the load.

3) Relative standard: As a relative standard for comparing power levels.
4) Stepwise Variable Optical Attenuator used in radar anti-interference: It is a variable attenuator with sudden change in attenuation. It does not introduce attenuation at ordinary times, but suddenly increases attenuation when encountering external interference. From the perspective of microwave network, the attenuator is a two-port lossy microwave network. It belongs to the through-type microwave element.
