In this paper an upgraded two stage branch dividing/combining network is designed to improve the VSWR
amplitude and phase characteristic.During the design the factors that will influence the combining efficiency and the fabricating precision of the millimeter-wave band are considered synthetically
all those ensure the good combining efficiency of this network.Based on the network a millimeter-wave solid state amplifier with high performance is developed.In the band of 38-40GHz the minimum output power of the amplifier is more than 34.8dBm and the minimum gain is more than 55dB.The results show that this amplifier has good electrical performance
simple structure and is easy to be fabricated as well.
