| | | WWW, re: iPhone 12 mmW supplier- QCOM v USI .............................
With the news of iPhone 12 having a USI moniker on their mmwave antenna package it's all still a bit confusing.
Thanks for the info on QCOM and USI (ASE) cooperation. I haven’t found a whole lot of info on their website (19k employees) that indicates much if any experience in RF components / wireless design (except antennas) including power amplifiers, filters, envelope tracking, transceivers.
This recent (sept 2020) news item is also interesting as it references another tie-up with QCOM with SiP orders for Wi-Fi 6E modules, however the rest of the article is behind a paywall.

Below is their info on miniaturization- Antenna on Package.
Perhaps as you mentioned they still work with QCOM, using QCOM’s RF components and package them with their antenna on a smaller package for the iPhone using the USI part number.

Antenna on Package
Miniaturization becomes much more important, especially for mobile devices, Internet of Things (IoT) and wearable electronics. By integration of these miniaturization solutions, most electronic systems can reduce size to meet market requirements.
Miniaturization brings the following benefits.
Size (XY) reduction to have more space for battery and integrate more functions
Reduce thickness (Z) and weight for stylish ID design
Reduce final assembly, test & pack difficulty
Improve signal integrity
EMI shielding interference
Speed up development
Better reliability-humidity and mechanical
Better logistics and inventory management |
