Abstract

Die Erfindung gibt ein Verfahren zur Signalverarbeitung eines amplituden- und/oder phasenmodulierten Hochfrequenzsignals (RF-Signal), bei dem das RF-Signal in zwei Signale (FM1 und FM2) durch relative Phasenverschiebung um einen Winkel +β und -β zerlegt wird und die Signale verstärkt werden, bevor sie zu einem Sendesignal addiert werden, und eine Schaltungsanordnung an, bei der das rein phasenmodulierte RF-Signal in einem ersten Zweig mit cosβ und in einem zweiten Zweig mit sinβ multipliziert wird und die beiden Signale (FM1, FM2) durch jeweilige Summen- und Differenzbildung der multiplizierten Signale gewonnen werden.
