Abstract
A transmitter into which a modulated signal (TX) is fed, the transmitter comprising an adjustable amplifier () for adjusting transmission power level, the modulated signal (TX) being fed into to the input of the amplifier (), an amplification branch () arranged after the adjustable amplifier () on the signal path, the amplification branch comprising a power amplifier () for further amplifying the transmission power level, and at least one filter () arranged after the power amplifier () on the signal path for filtering the frequency band to be transmitted. The transmitter further comprises an antenna () after the amplification branch () on the signal path for transmitting signals. The transmitted is characterized by a bypass branch () which operatively couples the output of the adjustable amplifier () and the antenna () and is used for bypassing the amplification branch () and connecting signals to be transmitted at low transmission power levels directly to the antenna ().
