<p>There is provided an apparatus, having a first local oscillator (130) generating a first oscillation signal, a first mixer (116) generating a transmit signal by mixing an input signal and the first oscillation signal, an observation receiver receiving a portion of the transmit signal, and applying, in a first operation mode of the apparatus, the received portion of the transmit signal such that a transmit signal component on a frequency of the first oscillation signal falls into a band-pass frequency of the observation receiver, and shifting, in a second operation mode of the apparatus, the received portion of the transmit signal such that an oscillation leakage signal component of the first oscillation signal falls into the band-pass frequency of the observation receiver; and a compensation unit (110) generating a compensation signal based on the band-pass signal of the observation receiver for compensation of the input signal.</p> |
