Abstract
The present invention relates to a method and a device for the I/Q demodulation of modulated RF signals. The I/Q demodulator () has a first input for the RF signal () to be demodulated and a second input for a RF signal () originating from a local oscillator (). The demodulator () combines the two RF signals () to generate three output signals supplied to three power detectors. In a combination unit () the three power signals of the power detectors are merged in two signal branches wherein after passing an A/D converting () and digital processing unit () one signal is the I component and the other one is the Q component of the received modulated RF signal ().
