<p>The invention relates to a power varying circuit. In order to be able to provide an improved performance of such a circuit it is proposed that by employing a switch (10), a received signal can be forwarded either to a first signal path (11) amplifying signals passing through with a first amplification factor or to a second signal path (12) amplifying signals passing through with a second amplification factor. Coupling means (6) to which an output of said first signal path (11) and an output of said second signal path (12) are connected couple at least a portion of signal leaving said first signal path (11) to an output terminal RF_OUT and couple a portion of signals leaving said second signal path (12) to said output terminal RF_OUT. The invention equally relates to a radio transmitter, to a radio terminal and to a corresponding method.</p> |
