Abstract

Es ist eine rauscharme Verstärkerschaltung angegeben, welche ein umschaltbares Verstärkungsverhältnis aufweist. Hierfür ist zwischen einem hochfrequenten Signalein- und -ausgang (1, 2) eine Parallelschaltung aus einem ersten und einem zweiten Strompfad (3, 4) vorgesehen, wobei der erste Strompfad (3) zur Signalverstärkung einen Transistor in Basisschaltung und der zweite Strompfad (4) zur Signalverstärkung einen Transistor in Emitterschaltung (7) mit einer Eingangsimpedanzanpassung (25, 27) aufweist. Aufgrund der guten Rauscheigenschaften sowie der guten Linearitätseigenschaften ist die beschriebene rauscharme Verstärkerschaltung zum Einsatz in Hochfrequenzempfängern geeignet, bei denen auf Grund eines großen Dynamikumfangs des Eingangssignals, wie beispielsweise bei UMTS, eine adaptive Vorverstärkung noch vor einem Frequenzumsetzer, das heißt in der Hochfrequenzebene, benötigt wird.
