skrf.qfactor.Qfactor.Q_unloaded

Qfactor.Q_unloaded(opt_res=None, A=None)[source]

Unloaded Q-factor Q0.

The value of the unloaded Q-factor Q0 cannot be measured directly but can be estimated from the measurement of the loaded Q-factor Q_L [MAT58] .

opt_resNone or OptimizedResult. Default is None.

Solution produced by the fit() method. If None, uses the solution previously calculated, if performed.

Afloat or None. Default is None.

Scaling factor as defined in MAT 58 [MAT58]. For reflection resonance type, can be set as None to use the magnitude of the fitted detuned reflection coefficient S_V
