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 component 220 for 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 component 231 having a first terminal 232 for receiving the first signal, a second terminal 234 for outputting the second signal, and a third terminal 236 for receiving the first cancellation signal, wherein the mixing component 231 is adapted to provide the second signal as output at the second terminal 234 by mixing the first signal provided as input at the first terminal 232 and the first cancellation signal provided as input at the third terminal 236.

Abstract: An inductor layout (200, 300, 400) comprising a first inductor (210, 310, 410) and a second inductor (220, 320, 420). The first and second inductors (210, 310, 410; 220, 320, 420) are electrically and magnetically independent inductors concentrically arranged on an integrated circuit 800. At least one of the first and second inductors (210, 310, 410; 220, 320, 420) is a multi-loop inductor with a first axis (226a, 316a, 326a, 416a, 426a) of symmetry.
