I/Q demodulator device with three power detectors and two A/D converters |
摘要 |
The present invention relates to a method and a device for the I/Q demodulation of modulated RF signals. The I/Q demodulator (60) has 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) combines the two RF signals (61,62) to generate three output signals supplied to three power detectors. In a combination unit (70) the three power signals of the power detectors are merged in two signal branches wherein after passing an A/D converting (72) and digital processing unit (73) one signal is the I component and the other one is the Q component of the received modulated RF signal (61).
