Low Temperature Co-fired Ceramic (LTCC) technology is a multi-layer ceramic process that can be used to fabricate low cost, high performance RF and microwave components. It is an extremely versatile technology that can be used to realise a wide range of components from simple passive filter structures and packages to complex sub-system assemblies containing discrete SMT (Surface Mount Technology) components, bare die and printed passives. This paper presents an overview of the LTCC fabrication process and details an on-going programme of work aimed at providing the detailed RF characterisation data that designers require in order to fully exploit the benefits of the technology. Measured material characterisation data is presented for a number of diffe
