iPhone 12 and 12 Pro iFixit Teardown..............................................................

Snips 12 and 13 from iFixit’s teardown reveal QCOM’s SDX55M 5G modem, an LTE transceiver (SDR865), and SMR 526 intermediate frequency IC.

However, Step 13 shows the antenna module is made by USI as well as the ultra-wideband chip.

Thus, this contradicts the recent BoA report which stated all iPhone 12 models contained QCOM antenna modules for mmW. The QTM525 contains several componets as indicated below>>>>....”...with separate power amplifiers, filters, envelope tracking, antennas, transceivers, etc for the mmWave spectrum. Qualcomm packages these mmWave components into a single module, dubbed a millimeter wave module (QTM525), ...”

Does the AAPL antenna module manufactured by USI also contain all the components mentioned above?

If so, BoA has a lot of explaining to do.

Step 12-


o A little heat (a lot of heat) and a little prying yields two boards for the price of one! We split one of the iPhone 12 boards open to get a look at all that sweet silicon, and if it seems hard to guess which one, you're not alone—the logic boards of the 12 and 12 Pro are nearly identical, apart from a few serial numbers.

o Apple APL1W01 A14 Bionic SoC, layered over Micron D9XMR MT53D512M64D4UA-046 XT:F 4 GB LPDDR4 SDRAM (6 GB RAM on the 12 Pro)

o KICM224AY4402TWNA12029, likely 64 GB of Samsung flash storage.

o Qualcomm SDR865 5G and LTE transceiver

o Qualcomm SDX55M 5G modem-RF system and SMR526 intermediate frequency IC

o USI/Apple U1 ultra-wideband chip

Avago 8200 high/mid power amplifier

Step 13 >>


o Our US models come with some of these nifty 5G mmWave antenna modules—one embedded in the side of the frame, and another on the back of the logic board.

o We think these have something to do with what Apple spent so much time talking about during their keynote?

o The antenna in the frame is made by USI, and we spot some numbers and letters on its face: 339M00104 S30U7FH
