Attenuation of three link microwave attenuator¶

Microwave attenuators are used to attenuate the microwave signal. For a three-link T-type attenuator or a π-type attenuator, the signal attenuation coefficient is calculated from the ratio of resistances of the resistors.

attenuation¶: attenuation of the attenuator.
