摘要

本文基于低温共烧陶瓷（Low Temperature Co-fired Ceramic，LTCC）三维封装技术，通过将多节四分之一波长阻抗变换线进行折叠布局和垂直堆叠设计，实现了多节宽带功分器的高度集成.本设计将7节阻抗变换线分别放置在LTCC介质的奇数层上，相邻阻抗变换线之间采用垂直过孔进行连接，偶数层用来隔离阻抗变换线之间的耦合效应.该功分器不仅实现了180%的相对带宽，而且尺寸仅为4 mm × 4 mm × 1.33 mm.相比同样传输节数平面型功分器，本设计的水平尺寸减小了84.6%.在2~38 GHz的频率范围内，

Abstract

Based on the low temperature co-fired ceramic (LTCC) three-dimensional packaging technology

this paper folds and vertically stacks multiple quarter-wavelength impedance transformation lines to achieve high integration in a multi-section broadband power divider. This design places 7 impedance transformation lines on the odd layers of the LTCC medium

and vertical vias are used to connect adjacent impedance transformation lines. Even layers are used to isolate the coupling effect between impedance transformation lines. The power divider not only achieves a relative bandwidth of 180%

but also has a size of only 4 mm ×

4 mm × 1.33 mm. Comparing with the planar power divider with the same number of transmission sections

the horizontal size of this design is reduced by 84.6%. In the frequency range of 2~38 GHz

the measured values of

and
