Abstract

Die Erfindung betrifft ein Mobilfunkgerät und ein Verfahren zum Betrieb eines Mobilfunkgerätes mit einem Leistungsverstärker (1), wobei der Leistungsverstärker (1) mindestens einen Eingang für ein Ansteuersignal (8), mindestens einen Eingang für eine Versorgungsspannung (7.X) und mindestens einen Ausgang für ein Ausgangssignal (13) aufweist. Die Erfindung zeichnet sich dadurch aus, daß mindestens eine Vorrichtung (4, 5, 6) zur laufenden, mittelbaren oder unmit-telbaren Bestimmung der Pegelgröße des Ansteuersignals (8) des Leistungsverstärkers (1) und mindestens ein schnell steuerbarer Schaltregler (3) zur laufenden Anpassung der notwendigen Versorgungsspannung (7.1) an die Pegelgröße, vorgesehen sind.
