METHOD AND ARRANGEMENT FOR CONTROLLING THE OPERATION OF A HIGH-FREQUENCY POWER AMPLIFIER

摘要

The invention relates to a method and an arrangement for controlling the operation of a high-frequency power amplifier. The arrangement comprises a high-frequency power amplifier (1) connected to a forward line (A) and a control means (2) and an attenuation means (3) connected to the input side thereof. A sampling means (4) and a detector (5) means are connected to a feedback line (B) between the output side and the input side of the high-frequency power amplifier. An amplifying means (7) is connected to the feedback line (B) on the input side of the detector means (5), the gain of which means is of the same order of magnitude as the attenuation of the attenuation means (3).
