    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 invention concerns a device for correction of the phase due to C class operation of a "solid state" amplifier. The invention is applicable in the manufacture of pulsating radar emitters. "Solid state" amplifiers are likely to give rise to phase variations. The invention concerns a measuring and correcting loop, whereby heat-induced phase variations may be eliminated in real time.

    Abstract: A distortion compensating apparatus calculates a distortion compensation coefficient in such a manner that a difference signal between a reference signal, which is a transmit signal, and a feedback signal will be diminished, updates an old distortion compensation coefficient by the calculated distortion compensation coefficient and applies distortion compensation to the transmit signal based upon this distortion compensation coefficient. In this apparatus, a phase correcting interval, which is for correcting the phase difference between the reference signal and the feedback signal, and a distortion compensation coefficient updating interval are generated alternately, a correction is applied so as to null the phase difference in the phase correcting interval, and the distortion compensation coefficient is updated in the distortion compensation coefficient updating interval.

    Abstract: A high frequency SSB radio transmitter has an envelope amplitude modulator (3) for varying the envelope of an r.f. signal source based on an error signal from envelope detectors detecting the envelope of the input and output waveform. It also has a phase modulator (4) in a main feedback loop for varying the phase of the input waveform based on differences detected in phase detector (10) between the instantaneous phase of the input and output r.f. signal. To overcome the problem of spurious outputs from phase detector (10) resulting from the cross-over points of the SSB waveform when there are carrier breaks and other problems, a subsidiary, phase lock loop (12) feeds a signal derived from the error signal to phase modulator (13) to tend to hold the input A, B in such a phase relationship that the output is zero. To cope with large phase shift errors between input waveform and output resulting from when the power amplifier changes frequency or temperature variations e.g. at the antenna, a broadband phase shifting network (17) is brought into operation when a dual voltage comparator (19) senses that the signal fed to modulator (13) passes a value corresponding to its extremes of adjustment.
