摘要
介绍了一种基于LTCC(低温共烧陶瓷)技术的小型化balun的设计。设计的Balun采用Marchand balun结构,使用LTCC技术实现多层结构、上下耦合的方式减小balun的体积并拓展带宽。该balun工作在1.7～2.2GHz,体积为2.8mm×3mm×1mm,并且平衡端口输出具有良好的幅值平衡和180°相位差。
In this paper, we present a miniaturized low temperature co-fired ceramic (LTCC) balun. The size of Marchand balun is reduced by the LTCC mulilayer technology and the broadband is improved by using vertical solenoid coupled transmission lines. The designed balun shows the maximum amplitude imbalance of 0.1 dB and the maximum phase imbalance of 5 in the 1.7～2.2 GHz frequency band. The overall dimension is as small as 2.8 mm× 3 mm×1 mm.
