摘　　要：在微波电路集成中,为了满足电路小型化的需求,通常使用埋入式电感等集成无源元件。但电感模型比较复杂,寄生参数较多,在版图设计当中难以一次性建立精准的模型。针对此问题,文中以埋入式集总参数功分器为例,基于ADS仿真软件,在添加可调的理想电感、电容后对功分器进行场路联合优化设计仿真。以功分器设计指标作为优化目标进行优化计算,得出可调的理想电感、电容值,再不断修改版图并循环优化。结果表明,可调的理想电感、电容数值逼近0,3次优化后工作频段9.5~9.9 GHz内的回波损耗S11低于-22 dB,满足-20 dB以下的性能指标,说明功分器的版图符合设计要求。The integrated passive components such as embedded inductors are usually used in the microwave circuit integration to meet the requirements of circuit miniaturization. Due to the complexity of the inductive model and too many parasitic parameters,it is difficult to establish an accurate model at one time in the layout design. To solve this problem,the embedded lumped parameter power divider is taken as an example. Based on the ADS simulation software,the field-circuit joint optimization design simulation of the power divider is carried out after adding adjustable ideal inductance and capacitance. The design index of the power divider is taken as the optimization target to carry out the optimization calculation,by which the adjustable ideal inductance and capacitance can be obtained. After that,the layout is modified continuously and optimized cyclically. The results show that the adjustable ideal inductance and capacitance values are close to 0,and the return loss S11 in the operating frequency band of 9.5~9.9 GHz is lower than-22 dB after three optimizations,which can satisfy the performance index below-20 dB. It indicates that the layout of the divider can meet the design requirements.
