摘要

针对宽带功率分配器面积大、回波损耗差等问题，本文提出了一款基于阻抗补偿技术的毫米波超宽带威尔金森功率分配器.在传统集总功分器输出端口添加并联LC谐振网络，可以补偿功分器的输入和输出阻抗并引入额外的匹配和无损耗频率点，进而有效地提高功分器的分数带宽.提出的功率分配器采用65 nm互补金属氧化物半导体（Complementary Metal Oxide Semiconductor，CMOS）工艺设计并测试验证，核心面积紧凑，仅有0.021 mm

.测试结果表明，该功分器的插入损耗为1.35~1.55 dB，0.2-dB幅度带宽为44~96 GHz，输入输出回波损耗和隔离性能在整个工作频段内均优于11 dB.与已发布的毫米波功率分配器相比，提出的功率分配器在保持良好端口匹配的同时实现了较高的幅度带宽.

Abstract

In this paper

a millimeter-wave ultra-wideband Wilkinson power divider with impedance compensation technique is presented. After adding parallel LC resonance networks at the output ports of traditional lumped-element power divider

the bandwidth can be increased effectively by compensating the input-output impedance and introducing additional matching and lossless frequency points. The proposed power divider is implemented using 65 nm complementary metal oxide semiconductor (CMOS) technology with a compact core area of 0.021 mm

. And the measurement results indicate that the insertion loss is 1.35~1.55 dB

reaching 0.2-dB amplitude bandwidth of 44~96 GHz

as well as the input-output return loss and isolation performance are all better than 11 dB across the entire operating frequency band. The proposed power divider achieves higher amplitude bandwidth with good port matching compared to previously published power dividers.
