摘要/Abstract

摘要：

提出一种用等效电路代替λ/4传输线的小型化射频功率分配器设计方法．采用介电常数为5.9的 Ferro A6多层低温共烧陶瓷基板设计了一款中心频率为1.616GHz、带宽为200MHz的3dB功率分配器．测试结果表明，其性能可与威尔金森功率分配器相比拟，而整体体积仅为3.2mm×1.6mm×0.9mm，小于威尔金森功率分配器尺寸的1/10．

关键词: 功率分配器, λ/4传输线, 低温共烧陶瓷

Abstract:

A miniaturized power divider design method by replacing the λ/4 transmission line with an equivalent circuit is proposed. By using Ferro A6 LTCC substrates with the multi-layer dielectric constant of 5.9, a bandwidth of 200MHz, the center frequency of 1.616GHz multilayer power divider is designed and measured by use of Low Temperature Co-fired Ceramic (LTCC) technology. Its performance can be comparable to the Wilkinson power divider, with its size being 3.2mm×1.6mm×0.9mm, which is less than 1/10 of the Wilkinson power divider.

Key words: power divider, λ/4 transmission line, low temperature co-fired ceramic
