The invention relates to a method for com-pensating amplification variations in an amplifier circuit comprising high-frequency components and attenuators, a high-frequency component being controlled with a first temperature-dependent control voltage U HF(T) and an at-tenuator being controlled with a second temperature-de-pendent control voltage U VG(T). The first temperature-de-pendent control voltage U HF(T) is generated by impressing a temperature dependency on a control voltage U opt which is individual of a high frequency component and which is predetermined at a predetermined temperature, to adjust the optimum operating point of the high frequency com-ponent, and the second temperature-dependent control voltage U VG(T) is generated by impressing a temperature dependency on a predetermined control voltage U VG_T for the attenuator, the control voltage U VG_T being determined by adjusting the control voltage U VG_T in an iterative me-thod in such a manner that the output power of the ampli-fier circuit reaches a level at a constant input power, which level can be predetermined. The invention further relates to a device comprising memory units for per-manently storing values for generating control voltages for the high frequency components and attenuators and electrical circuits having an input and an output for gene-rating a temperature-dependent output voltage while ta-king into consideration a temperature-dependent input voltage U IST(T) applied to the electrical circuits and a value stored in the memory units, the stored value corresponding to an indi-vidual control voltage U opt for adjusting the optimum operating point of the high frequency components. |
