<p>An amplifier mixer device includes an amplifier structure having at least one amplifier input and at least one amplifier output. At least one of the amplifier outputs is looped back via a feedback to at least one of the amplifier inputs. The amplifier structure includes a mixer structure. The mixer structure comprises at least one switch having a switch input communicatively connected with the radio input, and a switch output communicatively connected with the mixer output. The switch input and switch output in a conducting state of the switch are electrically connected with each other and in a non-conducting state of the switch are electrically substantially not connected with each other. In use, the switch is switched from the conducting state to the non-conducting state and vice versa with the local oscillator signal.</p>
