Abstract
A transceiver with amplification control comprises the following. A coupler samples a part of a radio frequency signal proceeding between an amplifier unit and an antenna of the transceiver. A converter down converts the sampled radio frequency signal. A measuring unit measures strength of the down converted radio frequency signal. A controller controls at least one parameter of the amplifier unit as a function of the measured strength.
