Abstract

The present invention relates to an RF power amplifier in which the added noise transmitted is greatly reduced. The invention applies for example in co-located RF transmission and reception systems belonging to different telecommunication networks, where each system is liable to pollute the other. The power amplifier comprising at least one transistor (Q1), the said transistor comprising a feedback circuit (10) determining its amplification gain, it furthermore comprises a feedback circuit (30) effective in a base frequency band in which noise is produced at the output of the said transistor, so that a part of the output noise is injected at the input of the said transistor.
