Narrative:

On arrival into denver, we were given several vectors that had us follow much slower turboprop aircraft, causing an RA between us and a dash 8. We maneuvered to follow the RA command. We were then given a turn north due to our altitude and vectored on final -- '120 degrees' to intercept runway 16R. At that time, we were already in a 30 degree bank to comply and told to make it a 'tight turn, really tight' and further resulted in a 2ND RA between us and an EMB120 on approach to runway 16L. We again maneuvered to comply with the second RA. I believe the problem occurred by trying to sequence an rj with much slower turboprops.

Narrative: ON ARR INTO DENVER, WE WERE GIVEN SEVERAL VECTORS THAT HAD US FOLLOW MUCH SLOWER TURBOPROP ACFT, CAUSING AN RA BTWN US AND A DASH 8. WE MANEUVERED TO FOLLOW THE RA COMMAND. WE WERE THEN GIVEN A TURN N DUE TO OUR ALT AND VECTORED ON FINAL -- '120 DEGS' TO INTERCEPT RWY 16R. AT THAT TIME, WE WERE ALREADY IN A 30 DEG BANK TO COMPLY AND TOLD TO MAKE IT A 'TIGHT TURN, REALLY TIGHT' AND FURTHER RESULTED IN A 2ND RA BTWN US AND AN EMB120 ON APCH TO RWY 16L. WE AGAIN MANEUVERED TO COMPLY WITH THE SECOND RA. I BELIEVE THE PROB OCCURRED BY TRYING TO SEQUENCE AN RJ WITH MUCH SLOWER TURBOPROPS.
