得奖 is a separable verb (离合词) meaning to win a prize or award. The verb 得 and the noun 奖 can split when you insert a measure word, duration, or aspect marker between them — for example, 得了一个一等奖 ('won a first prize'), 得过大奖 ('have won a major prize'), 得了三次奖 ('won three times'). The object of the award (what prize) is usually placed after 得奖 as a modifier, e.g. 得了诺贝尔奖 ('won the Nobel Prize'), or you can use 获得 as a more formal synonym.
