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).
摘要（中）：

本发明涉及用于调制RF信号的I / Q解调的方法和装置。 I / Q解调器（60）具有要被解调的RF信号（61）的第一输入和源自本地振荡器（20）的RF信号（62）的第二输入。 解调器（60）组合两个RF信号（61,62）以产生提供给三个功率检测器的三个输出信号。 在组合单元（70）中，功率检测器的三个功率信号被合并在两个信号分支中，其中在通过A / D转换（72）和数字处理单元（73）之后，一个信号是I分量，另一个是 所接收的调制RF信号（61）的Q分量。
