摘　　要：分析了传输线变压器混合网络特性,通过多级传输线网络组合,实现了短波宽带七路同相功率合成器。该合成器在工作频带1.5～30 MHz范围内,具有阻抗平稳、低插入损耗、高隔离度的特点,实际测试结果表明：合成器最大插损小于0.4dB,各端口幅度不一致性小于0.2dB,相位不一致性小于1°,能够实现无失真功率输出。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.
