One issue they didn't mention, but probably shows up in the noise figures is that homodyne receivers suffer from 1/f noise in the relatively wide band "direct conversion" amplifiers. Of course all of the heterodyne receivers suffer from 1/f up-conversion at the mixer.
- teleforce 3y agoIt is rather a soup of terminologies namely homodyne, zero-IF, and direct conversion architecture are all referring to the same thing. It seems they are now settling on RF sampling for the newer transciever architecture technology but sometime direct RF is also being used for example this latter terminology is referred by Intel for their new line of FPGA and RF transceivers product integration.
