摘要

杂化是微波器件中最重要的一种，其小型化是当今的热点。根据定向耦合器单支路耦合线路的设计原则，分析了影响耦合系数和隔离度的因素。本文在LTCC和HFSS的基础上，提出了一种新的带状结构混合电路，其隔离度小于-35dB，尺寸为3.2mm×3mm×1.2mm。最终实现了混合动力汽车小型化的目标。

Design of a stripline-structured hybrid based on LTCC technology

Hybrid is one of the most important microwave devices, whose miniaturization is a hot topic nowadays. According to the design principle of single-branch coupling line of directional coupler, factors that influence coupling coefficient and isolation are analyzed. Based on LTCC and HFSS, a novel stripline-structured hybrid is demonstrated in this paper, the isolation of which is less than -35dB and with dimension 3.2mm×3mm×1.2mm. Goal of miniaturizing the hybrid is finally realized.
