Abstract

Es ist eine Schaltungsanordnung zum Bereitstellen eines komplexwertigen Lokaloszillator-Signals angegeben, welche zwei Doppelmischer (M1, M1', M2, M2') umfasst, die von einer Signalaufbereitungsschaltung (1) mittels eines an einem Eingang (E, E') zuführbaren Bezugssignals so an ihren Eingangspaaren angesteuert werden, dass an den zur Frequenzumsetzung ausgelegten Doppelmischern ausgangsseitig (A, A') eine Inphase- und eine Quadratur-Komponente, welche zueinander eine exakte Phasenverschiebung von 90 Grad aufweisen und gemeinsam ein komplexwertiges Lokaloszillator-Signal bilden, bereitgestellt ist. Die Schaltungsanordnung ist bevorzugt in einem Empfänger zum Ansteuern eines Abwärts-Frequenzumsetzers (12) anwendbar. Das vorliegende Prinzip ermöglicht eine Verringerung der Abhängigkeit der Frequenzverschiebung von 90 Grad von Fertigungstoleranzen, eine verringerte Frequenzabhängigkeit der Phasenverschiebung sowie eine deutlich geringere Stromaufnahme eines Mobilfunkempfängers.
