This paper analyzes the characteristics of mixed network for transmission line transformer,realizes the shortwave wideband 7-channel in-phase power synthesizer by means of multiple transmission line net combination.The power synthesizer has the characteristics of steady impedance,smaller insert loss,higher isolation in operating frequency band of 1.5~30MHz.The practical test results show:for the synthesizer,the max insert loss is less than 0.4dB,amplitude uniformity of each port is less than 0.2dB,phase uniformity is less than 1°,which can realize the distortionless of power output.
