This article addresses options for building advanced of resistive voltage dividers (attenuator), providing a reduction in a given number of once input voltage in a wide range of operating frequencies. To correct the frequency error in the AT parasitic capacitance the load is proposed modified scheme with the special frequency attenuator correction, which allows for one to two orders extend the range of working frequencies the AT and increase performance.
