In 2023 TSMC is to master the production of Apple 5G modems using 4nm technology

Apple’s systematic refusal to use modems developed by Qualcomm has already been resolved, since representatives of the latter recently admitted that in 2023 the company will receive no more than 20% of its core revenue from Apple. TSMC is set to master the production of Apple modems using 4nm technology by 2023, according to Asian sources.

Fresh rumors on this topic are analyzed by the publication Nikkei Asian Review… Apple, according to the primary source, is going not only to develop its own radio frequency circuit and module for operation in the millimeter wave, but also the accompanying power electronics. In the current generation of iPhones, all of these components are Qualcomm-branded. Developing proprietary solutions of this type will ultimately allow Apple to integrate the modem into its mobile processors, as competing companies do. Since 2016, Intel has also supplied modems to Apple, but in 2019 it sold it a core business inherited from Infineon, and now specialists continue to work on the iPhone manufacturer’s staff.

During the development and prototyping phase, TSMC will use the existing 5nm process technology for Apple modems, but by the time mass production starts, it will give way to a more advanced 4nm process. The process of preparing a modem for serial production is stretched because of the need to test it for compatibility with the networks of telecom operators around the world.

In the second half of 2022, TSMC may also master the release of Apple’s mobile processors for the iPhone using 4nm technology, if rumors are to be believed. The use of 3nm technology for the release of Apple processors for iPad tablets may begin as early as next year. Apple’s mobile processors for the iPhone will only switch to 3nm technology in 2023.
