amplitude balance: the maximum peak-to-peak amplitude difference (in db) between the output ports of a
power divider or hybrid coupler over the specified frequency range.
attenuation accuracy: the amount of variation in magnitude from the nominal value across the entire frequency
band.
attenuator: a passive device or network that absorbs part of the input signal and transmits the remainder with
minimal distortion. attenuators are used to extend the dynamic range of devices such as power meters and
amplifiers, reduce signal levels to detectors, match circuits and are used daily in lab applications to aid in product
design. attenuators are also used to balance out transmission lines that otherwise would have unequal signal
levels.
