<p>The invention relates to a transceiver and a method for receiving a RF signal in a transceiver. The invention relates in particular to mobile stations of mobile telecommunication systems that employ both time division duplex (TDD) and frequency division duplex (FDD) to provide isolation between transmission and reception. An idea of the invention is to control (29) the bias of the LNA-type preamplifier (2) in the reception in such a manner that when receiving during transmission, a greater bias is used than when transmission is not taking place. This way the amplifier will have a great bias when a signal from the transmitter part (17-26) is coupled to the receiver part, and since increasing the bias will improve the linearity of the amplifier (2), less unwanted components will appear in the amplifier. The mean power consumption in the receiver will, however, remain reasonably small because a small bias will be used during the times when no transmission is taking place.</p> |
