摘要
为了实现Wilkinson功分器的宽频比双频工作特性,并简化功分器的总体结构,提出了采用耦合线和隔离枝节相结合的设计方法.和隔离电阻直接与端口连接的功分器形式相比,由隔离枝节构成的功分器结构减小了传输线间的寄生影响.设计并加工了工作在1.0 GHz和2.5 GHz频段的双频Wilkinson功分器,实验与仿真结果吻合,设计的功分器性能良好.
Design of a coupled line with a pair of isolation stubs is presented.Dual-band operation in the Wilkinson power divider can be achieved and also,the overall structure of the power divider can be simplified.Compared with the power divider directly connected by an isolation resistor,the one consisting of isolation stubs reduces the parasitic effects between transmission lines.A 1.0GHz,2.5GHz dual-band Wilkinson power divider is designed and processed.It is proved that simulation results agree with the experimental ones and the power divider works well.
