Medientyp: E-Artikel Titel: A simple stepped‐impedance transmission line load network for inverse Class F power amplifiers Beteiligte: Grebennikov, Andrei Erschienen: Wiley, 2011 Erschienen in: Microwave and Optical Technology Letters, 53 (2011) 5, Seite 1157-1160 Sprache: Englisch DOI: 10.1002/mop.25923 ISSN: 0895-2477; 1098-2760 Schlagwörter: Electrical and Electronic Engineering ; Condensed Matter Physics ; Atomic and Molecular Physics, and Optics ; Electronic, Optical and Magnetic Materials Entstehung: Anmerkungen: Beschreibung: <jats:title>Abstract</jats:title><jats:p>In this article, a novel simple load network with harmonic tuning, which is based on a stepped‐impedance transmission line is presented.Based on effect of a spectrum narrowing when poles of the reactance function are approaching adjacent zeros with higher transmission line impedance ratio, an open circuit at the second harmonic and a short circuit at the third harmonic are achieved, thus satisfying inverse Class F conditions.
