Abstract: A power amplifier arrangement has a first signal path which couples the input (1) to the output (2) and comprises a first amplifier (13), a second signal path which couples the input (1) to the output (2) and comprises a second amplifier (15), a control device (25) is coupled to the first signal path and the second signal path for activating and deactivating the signal amplifiers (13,15), depending on the required amplification, and at least one DC voltage converter (36) coupled to the first- and second-amplifiers. Independent claims are included for the following: (A) Application of the power amplifier arrangement.(B) Method for signal amplification.

Abstract: In a method for alignment of an antenna (1) with an adjustable directional characteristic in a mobile station in a mobile radio system, the alignment process is based on determination of two variables as a function of the direction, with the first variable being characteristic of the signal strength (6) and the second variable being characteristic of the signal quality (5, 15), and their evaluation (7). Furthermore, it is possible to make use of position information and alignment information relating inter alia to satellite-based navigation systems, and to take account of the alignment of the user.

Abstract: The circuit arrangement includes a main oscillator (HVCO) and a subordinate oscillator (SVCO) connected to the main oscillator. The main oscillator produces a signal with a x-th harmonic oscillation which is used to excite the subordinate oscillator. A divider is connected with the subordinate oscillator, and divides the frequency (fVCO) of an output signal (Sout) of the subordinate oscillator through an integer division value (n) which deviates from the value x. A feedback loop is preferably provided, which compares the output signal of the subordinate oscillator with a reference signal, and which provides a corresponding control signal to the subordinate oscillator.
