Ming-Chi Kuo has published a report that talks about the iPhone 2020 line. As expected, Kuo claims that Apple will begin launching the first iPhone 5G next year. The analyst also says that all three models will feature OLED displays. The report says the new devices will arrive in the new 6.7-inch, 5.4-inch and 6.1-inch screen sizes.
The 6.1-inch OLED model is apparently the successor to the iPhone XR and will only support LTE. The new 6.7-inch and 5.4-inch iPhones will support 5G.
For Qualcomm’s modem, Apple is thought to use its self-designed power amplifier and front-end module, instead of Qualcomm’s RF360. By using its own modified amplifier and module, Apple can lay the groundwork to more easily add its own version in a future update to the product line.
It is thought the 5G iPhone will support both sub-6GHz and frequencies above 6Ghz, due to the US being Apple’s home market. The mainstream technology for 5G in the United States is said to be mmWave, which would require the higher-than-6GHz frequencies to be supported, making a sub-6GHz-only iPhone unlikely.
For Apple customers who want a higher-end model with a smaller screen than what the current line offers, the 5.4-inch 5G OLED model seems to be the right one. The current iPhone XS is 5.8 inches diagonally, so a 5.4-inch model would represent a significantly smaller and more manageable device
On the other hand, we are talking about the iPhone XS Max, which will see its size increase, going from a 6.5-inch display to a 6.7-inch display.
5G compatibility in the iPhone 2020 will apparently support both main standards; that is, both the sub-6GHz technology and the mmWave technology.
Ming-Chi Kuo says Apple’s internal 5G band chip won’t be ready before 2022. This means that future generations of iPhones will depend heavily on Qualcomm’s chips to connect to high-speed 5G networks. However, Kuo believes that Apple is using its own power amplifier and its own RF antenna designs.
