Abstract
Three or more MESFETs are fabricated side by side on a semiconductor chip. A transmission line substantially identical in width with an area within which the MESFETS are fabricated is formed in parallel with the row of MESFETs. The MESFETs are connected to the transmission line at a side, constituting one edge of the transmission line. Further, regulation circuits are connected in shunt with the transmission line, and outputs of the MESFESTS are merged while being matched by the transmission line and the regulation circuits.
