Patent ID: 8547158

Claim:
A resistive mixer comprising: a transmission line which includes a first and a second electrical conductor each having a respective connecting contact being connectable to a source of an electrical high-frequency signal so that the electrical high frequency signal can be coupled into the transmission line, wherein the first conductor has a plurality of series-connected voltage-dependent resistor elements, whose resistively depend on the voltage locally occurring at the resistor elements, and wherein a capacitive element is arranged between the first and second conductors, characterised in that the voltaqe-dependent resistor elements are field effect transistors each having a source (S), a drain (D), a qate (G) and a source-drain channel, wherein the gates of all field effect transistors are so electrically connected together that the gates (G) form the second conductor and wherein the drain of a first field effect transistor is connected to the source of a second field effect transistor so that the source, the source-drain channel and the drain of the first field effect transistor and the source, the source-drain channel and the drain of the second field effect transistor form the first conductor.
