Turning downwind at FFFAT both GPS went out. Turning a 9 mile base; the 'Transponder Fail' light illuminated. This was a known problem happening to all aircraft according to Denver Approach.
While descending through 14;000 feet into DEN; approximately 3NM North of the DEN airport; we lost both the L and R GPS signals. We also received an amber TERR FAIL message on both ND's. Reported signal loss to DEN approach.  They responded 'We have had many reports today of GPS signals out'.  The L and R GPS signals restored 5 min after landing and upon taxing into the gate.Upon departure from DEN; while climbing through 3;000 feet; lost both L and R GPS signals.   Reported signal loss to DEN departure.  They responded 'We have had many reports today of intermittent GPS signal loss.'  Shortly after the L and R GPS signal loss we also received a 'XPDR FAIL' light on the  Transponder.  Operation of GPS signals and Transponder returned to normal while climbing through 26;000 feet.Determine if GPS outage was related to 5G activation; Note: while in the DEN airport; personal cell phone displayed 5G WB was in use.
Flight crew reported both GPS and transponder failed on approach and departure into and out of DEN.
