摘要: 机载、星载、舰载相控阵雷达由于其特定的使用环境,需要体积小、重量轻、高性能、高可靠、低成本的微波组件。带腔体LTCC基板具有高密度布线、电阻、电容、电感的内埋以及芯片的埋置等特性,是制作机载、星载、舰载相控阵雷达微波组件理想的高密度基板。针对带腔体LTCC集成基板的制造技术,简单介绍其工艺流程,并对腔体成型这项关键工艺进行了分析,提出了相应的解决方法。

关键词: 微波组件, 腔体, LTCC集成基板

Abstract: For air-borne,satellite-borne and ship-borne phased array radars,the microwave modules with small size,lightweight,high performance and high reliability are needed because of their special environment.LTCC substrate with the proper-ties of high density,embedded R/L/C and chips has become an ideal high density substrate formicrowave modules.For the manufacturing technology of LTCC substrate with cavity,after introducing the fabrication procedure,the key manufacturing processes of cavity are analyzed,and the relevant solutions are suggested.

Key words: microwave modules, cavity, LTCC substrate
