基于SiGe工艺多抽头电感结构的紧凑型Wilkinson功分器OA北大核心CSTPCD

In order to solve the problems of high loss and large size of traditional Wilkinson power dividers,starting from the theoretical analysis of power dividers,a new compact broadband equal division power divider with multi tap inductor structure is designed by improving the traditional microstrip line structure and LC lumped structure,and introducing frequency compensation capacitors at the isolation resistor.The designed power divider is based on 0.18 μm SiGe BiCMOS process,and the RF/microwave electromagnetic simulation shows that in the frequency band range of 8-16 GHz,the distribution loss of the power divider is less than 0.8 dB,the isolation degree is greater than 20 dB,the port return loss is greater than 15 dB,and the core circuit ayout area is only 0.30 mm×0.25 mm,which can meet the design requirements of low loss,miniaturization,and high isolation of broadband power dividers.
