TMSC, the chipset manufacturing partner of Apple, will soon start producing Apple first-in house 5G modem chipset, as per a Nikkei Asia report. Apple has been trying to produce an in-house chipset for quite a while now. The company has acquired the majority of Intel’s model business that should allow it to shift away from Qualcomm. Qualcomm has been Apple’s main supplier for important chips that support cellular connectivity.
According to people familiar with the issue, Apple is looking to adopt TSMC 4nm chip technology. It will mass-produce its first in-house 5G modem chip based on that. They further added that the iPhone maker is developing its own radio frequency and millimeter wave components to complement the modem. Additionally, Apple is also looking to produce a power management chipset specifically for the modem.

Previous reports have hinted the same about Apple in-house chipset
The new report is in line with prior reports that Apple would release its own modem as part of the 2023 iPhone lineup. Moreover, Qualcomm stated last week that it is planning on only having a 20% share of modem manufacture for the 2023 iPhone. In most countries around the world, Qualcomm anticipates Apple will use its own modem solution. However, Apple will continue to rely on Qualcomm for select markets, at least initially.
According to a piece posted by Nikkei, Apple and TSMC are now testing production of Apple’s in-house modem designs using TSMC’s 5-nanometer process. However, they will switch to the more sophisticated 4-nanometer process for mass production. The flagship A-series chip in the 2022 iPhone range will be based on 4-nanometer technology. On the other hand, the A-series processors in the 2022 iPads and 2023 iPhones will be made with 3-nanometer technology.
