A type of power combiner was introduced using broadside-coupled lines. And its basic theory and operation model were discussed. Taking the L-band power combiner for example, and it was analog simulated using CAD technique. Comparing the simulation results with the actual measurement results, the difference between them is less than 0.3 dB, and it can meet the requirements of power combining. It also concerns the relationship between its design approach and engineering applications, which achieves great results in practice. This high-power combiner demonstrates better performances in insertion loss, balance of phase and amplitude, power handling capability, small size and convenient assembling and adjusting. It＇s a goal method for high-power combine.
