A B767 Captain reported that SAEZ's radios failed on all Center and Airport frequencies while his aircraft was on approach. The crew transmitted approach intentions in the blind; landed without incident and taxied to the gate. ATC's receivers failed.

Narrative

Approaching SAEZ; we were handed off from the Center to Approach Control. We were unable to raise Approach on the assigned frequency; so we switched back to the Center. We were unable to reach the Center either; so we switched to Tower; and then Ground Control...all without success. We heard other airplanes report their inability to communicate with SAEZ; and we heard another air carrier broadcast in the blind that they were clearing the runway. We reviewed TCAS; and broadcast in the blind that we were commencing the approach. We had previously been cleared direct ARSOT (the IAF). I asked the Relief Pilot to call SAEZ Company Operations; and to have the station telephone the Tower to let them know we were commencing the approach. Once established inbound; ATC regained their ability to transmit; but they were unable to hear. We were cleared to land Runway 11. The approach and landing were uneventful; and we reported clearing the runway. We were cleared to taxi to the gate; and we flashed our lights to confirm receipt of clearance.
