Abstract:
1. I/Q demodulator having a first input for the RF signal ( 61 ) to be demodulated and a second input for a RF signal ( 62 ) originating from a local oscillator ( 20 ), the demodulator ( 60 ) combining the two RF signals ( 61 , 62 ) to generate three output signals for power detectors, characterized by an analog combination unit ( 70 ) for combining three power signals (P 1 , P 2 , P 3 ) output of the power detectors to two signal branches (X 1 , X 2 ) for further digital processing to obtain I/Q values characterized in that the combination unit ( 70 ) comprises a splitting unit ( 7 ) for splitting one of the power signals (P 1 ) into two subbranches.
