摘　　要：针对耦合检波电路不同频率耦合信号大小差别较大的问题,设计一款宽带耦合器,保证在6.7-9.9GHz带宽内耦合平坦度≤±0.3dB。考虑到工程应用,该宽带耦合器采用微带结构设计,在传统微带耦合器的基础上,利用矩形齿的加载,拓宽耦合器带宽,提高带内平坦度。As a result,difference frequency with big difference amplitude by detector circuit,a broadband coupler have been designed,which make sure the coupling flatness less than or equal to 0.2dB.Due to the technical application,the broadband coupler designed by microstrip structure.Based on traditional theory of the coupler,the band and the flatness of the coupler have been improved by loading sawing gear.
