Zusammenfassung

Die in Handfunkgeräten der GSM- und DECT-Mobilfunksysteme benutzten Frequenzerzeugerkonzepte beruhen im wesentlichen auf dem Einsatz dreier von dem Sende- und Empfangssynthesizer angesteuerten abstimmbaren Ozsillatoren. Ziel der gegenwärtigen Arbeiten ist die Integration dieser Oszillatoren in bipolarer Technik. In dem Beitrag werden die Anforderungen der Oszillatoren aufgezeigt. Die Erhöhung des Integrationsgrades der Oszillatoren wird theoretisch und experimentell untersucht. Für GSM-Anwendungen werden teilintegrierte und für DECT-Anwendungen vollintegrierte VCO-Varianten demonstriert.

Abstract

The frequency concepts of GSM and DECT systems in mobile handsets consist mainly of three voltage controlled oscillators. The goal of this work is the integration of these oscillators with a bipolar technology. In this paper the requirements for the oscillators are shown. The possibilities of integration are examined theoretically and by experiment. For the GSM system a partly integrated solution is demonstrated and for the DECT system a fully integrated VCO is presented.
