The device that maintains the specified VSWR and absorbs all power in high loss state.
Accuracy/Linearity
In VVAs, the variation of the mean attenuation from the best straight line of attenuation vs. control signal transfer function.
Analog Attenuator
A unit where continuously variable attenuation level is controlled either by an applied current (driver-less unit) or applied voltage (unit with driver).
Attenuation Accuracy
The maximum deviation of the mean attenuation from the nominal value of the set attenuation in dB.
Attenuation Flatness
The attenuation variation from the mean attenuation over the specified frequency range for a given attenuation value in dB.
