Abstract: The invention relates to a method for the regulation of transmitted phase of a signal in a device (100) which is part of a system for electromagnetic signal transmission, in which system the transmitted signal has periods when it contains information and periods when it does not contain information. The method comprises the control of the modulation position of a phase shifter (110) which has a linear and a non-linear range, power amplification (120) of the signal, detection of unwanted phase shifts in the signal transmitted by the device (100) caused within the power amplifier (120), and the detection of the information content of the signal, and is characterized in that the phase shifter (110) is reset to a particular predetermined modulation position phi ini in the event of detection of the absence of information in the signal. The predetermined modulation position phi ini to which the phase shifter (110) is reset is preferably situated within the linear range of the phase shifter.

Abstract: The phase of a transmitted signal is regulated in a device which is part of a system for electromagnetic signal transmission. The transmitted signal has periods when it contains information and periods when it does not contain information. The modulation position of a phase shifter which has a linear and a non-linear range is controlled. Power of the signal is amplified. Unwanted phase shifts in the signal transmitted by the device caused within the power amplifier are detected, and the information content of the signal is detected. The phase shifter is reset to a particular predetermined modulation position in the event of detection of the absence of information in the signal. The predetermined modulation position to which the phase shifter is reset is preferably situated within the linear range of the phase shifter.
