iPad Wi-Fi + 3G: torn down
Bookending the iPad Wi-Fi + 3G unboxing from earlier today is the other classic staple of geekdom: the tear-down. As usual iFixit did the deed, and here's what they uncovered:
There are actually FIVE antennas in this iPad. Two antennas handle the cell reception -- one is in the RF window on top, the other attaches to the LCD frame. A single GPS antenna is also housed in the RF window on top. Just like the iPad Wi-Fi, there are two antennas that handle Wi-Fi / Bluetooth connectivity, one in the Apple logo and another to the left of the dock connector.
Apple looks to be using the entire LCD frame as an antenna!
Apple uses the same 3G baseband processor in both the iPhone 3GS and the iPad 3G.
The baseband processor in question is the Infineon 337S3754 PMB 8878 X-Gold IC. It was actually white-labeled on the production unit, but with enough sleuthing we were able to confirm its true identity.
The iPad 3G has a Broadcom BCM4750UBG Single-Chip AGPS Solution, whereas the iPhone 3GS uses an Infineon Hammerhead II package. Big win for Broadcom!
Head on over if you want to see the whole, sordid strip-down...
