Airport Extreme Chipset?

[SaltWaterHippo]

Hi there. I have a 17" MacBook Pro and I've been trying to find out what type of chipset is on the AirPort Extreme wireless card inside the laptop. I'm not sure if they use the same chip sets in the AirPort Extreme cards in all MacBook Pros. Even if theres a few different types I'd still like any information you have about either - I've not been having alot of luck and this would narrow my search. Any info or links e.t.c. would be appreciated.

Edit - I actually found it on the "About this Mac" More Info window.
