Rumor has it that ASE(Advanced Semiconductor Engineering), a Taiwanese company has joined the supply chain for Apple and will manufacture the mmWave-based modules is circulating.
Apple will soon join the 5G world and reports suggest that the company’s roadmap includes at least one 5G iPad and 5G iPhone in 2020, but the company is yet to determine the provider of the technology.
The difference between mmWave and Sub-6 GHz technology is that the mmWave allows for faster data transmission but has much worse coverage. Apple’s plans on supporting both standards or just mmWave are not yet certain.
There’s some competition between ASE and TSMC for the Apple contract, but they are using a different technology. ASE is relying on FC_AiP (flip-chip antenna-in-package) technology that is cheaper, but uses bigger modules than the competing InFO_AiP technology.
