Abstract
The present disclosure generally relates to the field of receiver structures in radio communication systems and more specifically to passive mixers in the receiver structure and to a technique for converting a first signal having a first frequency into a second signal having a second frequency by using a third signal having a third frequency. A passive mixer for converting a first signal having a first frequency into a second signal having a second frequency by using a third signal having a third frequency comprises a cancellation componentfor generating a first cancellation signal for cancelling second order intermodulation components by superimposing the first signal weighted by a cancellation value on the third signal; and a mixing componenthaving a first terminalfor receiving the first signal, a second terminalfor outputting the second signal, and a third terminalfor receiving the first cancellation signal, wherein the mixing componentis adapted to provide the second signal as output at the second terminalby mixing the first signal provided as input at the first terminaland the first cancellation signal provided as input at the third terminal
