Zero IF is the AD9361/AD9364 architecture that's why there was a discussion about this.
16:32:46 From mnapier : I don't see how to raise my hand, looking.... 16:33:10 From Michael Kirkhart : Nice to hear you talk again - I attended the GNU Radio conference about 2 weeks ago (on-line). 16:51:44 From Fred Harris : I have some papers on I-Q imbalance and DC cancelers as well as image reject canceling algorithms... 16:52:07 From Marcin Puchlik : Mr F. Harris, I would be interested 16:53:49 From Fred Harris : drop me an email fjharris@ucsd.edu will send them to you... 16:54:22 From Marcin Puchlik : Sure! Thank you so much, I am sending a mail asap :) 16:54:40 From Fred Harris : we all the imbalnces and toleranc effects of I-Q analog processing "Dirty RF" 16:54:55 From Fred Harris : spelling... 16:56:21 From Fred Harris : We call the imbalances and tolerances effects of I-Q analog processing ( including Image folding), "Dirty RF" 16:57:14 From Michael Kirkhart : I believe you are referring to the 5G FR2 bands. 16:58:01 From Michael Kirkhart : https://www.electronics-notes.com/articles/connectivity/5g-mobile-wireless-cellular/frequency-bands-channels-fr1-fr2.php
The "Low IF" digital radio architectures do not suffer from IQ imbalance and DC offset issues. Those issues apply only to "Zero IF" architectures.
