HIGH OUTPUT POWER AMPLIFIER, WIRELESS TRANSMITTER, WIRELESS TRANSMITTING AND RECEIVING DEVICE, AND HIGH OUTPUT POWER AMPLIFIER MOUNTING METHOD

摘要

It is an object to provide a high output power amplifier, a wireless transmitter and a high output power amplifier mounting method that are high in heat dissipation effect and low in cost. A high output power amplifier is comprised of a transistor with a lead wire extending from both side surfaces of a mold set on a heat radiation member to the outside, a bifacial wiring board that has an aperture where the heat radiation member is inserted and a wiring pattern on its one surface where the lead wire is electrically connected, and a case that receives the bifacial wiring board, wherein the high output power amplifier is further provided with a plate, one main surface of which is in contact with the inner wall of the case while the other main surface of which is connected with the heat radiation member and a wiring pattern of the other main surface of the bifacial wiring board.
