Quasi-3D Multi-Way Power Dividers in LTCC Technology George Passiopoulos, Kevin Lamacraft Nokia Networks, Camberley, UK Abstract: In this paper we propose a quasi-3D semi-monolithic design approach upon which 2-way and 8-way quasi-3D power dividers are implemented utilising Low Temperature Cofired Ceramic (LTCC) multilayer technology. Semi-lumped 3D circuit techniques and 2-level integration appro
