Abstract
A homodyne receiver (), comprising a first mixer () with an RF input port () and an LO input port () for an LO signal and an output port () for the output signal of the first mixer which is also arranged to be the output port of the homodyne receiver. The homodyne receiver () also comprises a control unit () for controlling signal leakage from the LO input port () to the RF input port () of the first mixer (). The control unit () is arranged to control the leakage in amplitude and phase so that second-order distortion products and third order distortion products which are created when the RF and LO signals are mixed in the first mixer () exhibit similar amplitudes but a phase difference of 180 degrees.
