iFixit’s teardown of the iPhone 12 has revealed that there are 3 mmWave antenna modules built by USI. USI is a Shanghai based SiP design and manufacturing company. This would be their first design win in the space. Apple ditching Qualcomm on this component despite using the rest of the Qualcomm X55 5G Modem RF system is quite the shocker. To emphasize the magnitude of this design win, every US phone shipment which included 5G mmWave to date has used antennas from Qualcomm.
