Abstract

Zur Einstellung der Abstrahlleistung (AL) der Antenne (AT) eines Funkkommunikationsgeräts (MS) wird ein Messsignal (PREF) für die in den Transmitterzweig (TZ) der Antenne (AT) zurückfließende Sendeleistung (ZSL) mittels eines Koppelelements (CO) erfasst. Dieses Messsignal (PREF) wird für die zurückfließende Sendeleistung (ZSL) von einer Steuer-/Auswertevorrichtung (SV) zur Erzeugung mindestens eines Steuerparameters (SP) herangezogen. Mittels dieses Steuerparameters (SP) wird zur Einstellung einer gewünschten Sendeleistung (SL) am Ausgang des Leistungsverstärkers (PAM) mindestens ein Stellparameter (V) des Leistungsverstärkers (PAM) geregelt oder gesteuert.For adjusting the emission power (AL) of the antenna (AT) of a radio communication device (MS), a measurement signal (PREF) for the transmission power (ZSL) flowing back into the transmitter branch (TZ) of the antenna (AT) is detected by means of a coupling element (CO). This measurement signal (PREF) is used for the returned transmission power (ZSL) by a control / evaluation device (SV) for generating at least one control parameter (SP). By means of this control parameter (SP), at least one setting parameter (V) of the power amplifier (PAM) is regulated or controlled at the output of the power amplifier (PAM) to set a desired transmission power (SL).
