About RF receiver I/Q modulation/demodulation
May 19th, 2017, 12:45pm
 
Hi all,

I know that I/Q modulation is for cancelling mirror images, but is I/Q modulation needed under all circumstances? For example, for a direct-conversion RF receiver using FMCW, is I/Q modulation necessary? Why? Also, to get deeper knowledge on this topic, do you have a reference to recommend?

Thank you very much!
