The Doublet: A New Building Block for Modular Design of Elliptic Filters
The Doublet: A New Building Block for Modular Design of Elliptic Filters Smain Amari* and Uwe Rosenberg** *Department of Electrical and Computer Engineering, Royal military College of Canada, Kingston, ON, K7K 7B4 Canada. e-mail: smain.amari@rmc.ca **Marconi Communications GmbH, Backnang, D-71522 Germany. e-mail: Uwe.Rosenberg@ieee.org. Abstract-- The paper presents a new building block for modul
Synthesis of lossy filters
1 Synthesis of lossy filters B.S.Senior, I.C.Hunter, J.D.Rhodes Institute of Microwaves and Photonics, School of Electronic and Electrical Engineering University of Leeds, LS2 9JT Abstract-- A new procedure for synthesising filters with finite dissipative loss is presented. This method enables filters with finite Q resonators to be directly synthesised while maintaining a prescribed selectivity
Quasi-3D Multi-Way Power Dividers in LTCC Technology
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
