I think you backed into the answer a little more here. He's tight, he squeezed an UTG raise big. His range is pretty well defined here, and hero isn't in good shape. In fact, he'd have to rely on implied odds to make a flop call here profitable long term. But let's punch in a range and look at the exact numbers since this is a somewhat common spot.
I think it comes down to often we add in AQs here, but I'm not sure I could do more than 20%. I put zero here:

70.64% 51.6006% 19.043% [QQ+(100), AKs(100), AKo(100), JJ(40),]
He probably does give up with AK almost always after the flop bet, but there's more of his range that beats you. I'd give up, or even consider folding pre unless I was deeper against this kind of opponent/situation.
