We have developed a novel GaAs-based MODFET with the breakdown voltage (BVdg) of 130V keeping the maximum drain current (Imax) over 300 mA/mm where double-recessed and offset gate structures are provided. This newly developed MODFET attained the output power of 200 W at a supplying voltage of 15 V and a quiescent drain current of 10 A, which is the highest output power exhibited by using GaAs based FET's ever reported.
