iFixit Teardown of the iPad 3G
Posted on May 1, 2010 by eli courey
iFixit has done a teardown of the iPad 3G. Here are a few interesting things they discovered.
- 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.
