    Abstract: Disclosed is an integrated circuit (100) comprising a mixer circuit and a transformer (101). Said mixer circuit is provided with an active mixer unit (102), a signal-amplifying unit (103), two reference oscillator connections (LO+, LO-), two high-frequency connections (RF+, RF-), and two intermediate-frequency connections (IF+, IF-). The inventive integrated circuit (100) is arranged such that the transformer (101) galvanically isolates the two high-frequency connections (RF+, RF-) from the active mixer unit (102).<>
