When we checked in with D01 Approach Controller he informed us of some GPS and ADS-B failures occurring near DIA; presumably from 5G interference.  About the time he cleared us for the ILS 35L Approach (23 miles out); both of our GPS's failed; which I reported to him.  When he switched us to Tower at 20 miles; our transponder failed as well; which I also reported.  We landed without event and the failures corrected themselves on the ground.
Air Carrier pilot arriving DIA reported GPS failure.
