An apparatus and a method for reducing drain modulation in a high power amplifier are provided, in which an adder supplies a current corresponding to a voltage reduced by a drain modulation, and a bias unit adds the current supplied from the adder to a DC bias and supplies the added current to a drain of a transistor. Accordingly, the drain modulation occurring in the transistor can be minimized and an output characteristic of the high power transistor can be improved.
