Patent ID: 7109795

Claim:
An amplifier-mixer device comprising: an amplifier structure having: at least one amplifier input for receiving an input signal and at least one amplifier output for outputting an amplified signal, while at least one amplifier output is coupled back via a feedback to at least one amplifier input, which amplifier structure comprises a mixer structure for mixing said input signal with a local oscillator signal, said mixer structure having: at least one radio input communicatively connected to the amplifier input, for receiving said input signal; at least one local oscillator input for receiving a local oscillator signal; and at least one mixer output for providing an intermediate frequency signal resulting from said mixing, wherein 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, which 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, which at least one switch including a switch control,connected to said local oscillator input, for switching said switch from the conducting state to the non-conducting state and vice versa wit the local oscillator signal.
