Huawei Pura 70 Ultra’s 5G Radios: A Deep Dive into RF Components
Explore the advanced 5G radio design of Huawei’s Pura 70 Ultra in this detailed analysis. Discover how Huawei continues to innovate with entirely ‘made in China’ RF components and dual satellite communication technology.
Huawei's Pura 70 Ultra smartphone is a testament to the company's commitment to leading-edge technology, particularly in the realm of 5G radio design. As part of Huawei’s ongoing strategy to develop entirely “made in China” components, the Pura 70 Ultra continues to build on the successes of its predecessors, the Mate 60 series. In this technical deep dive, we explore the key RF components of the Pura 70 Ultra, providing insights into how Huawei is refining its mobile radio architecture.
Huawei Pura 70 Ultra vs. Mate 60: RF Component Comparison
Our in-depth analysis at TechInsights has revealed that the Pura 70 Ultra shares a significant amount of its mobile RF architecture with the Mate 60 and Mate 60 Pro/Pro+. The table below compares the main RF components across these three models, highlighting the consistency in Huawei's approach to 5G radio design.
| Component | Pura 70 Ultra (HBP-AL00) | Mate 60 (BRA-AL00) | Mate 60 Pro/+ (ALN-AL80/AL10) |
|---|---|---|---|
| FR1 RF TCVR | HiSilicon T303263F1 | HiSilicon T303263F1 | HiSilicon FFY6633F1 |
| Wi-Fi/BT SoC | HiSilicon Hi1105GFCV120 | HiSilicon Hi1105GFCV120 | HiSilicon Hi1105GFCV120 |
| MSS SoC | CETC MSC06A | CETC MSC06A | CETC MSC06A |
| MHB L-PAMiD | Unidentified CN 2D6BYSE21 | Unidentified CN 2D6BYSE21 | Unidentified CN S111341A |
| LB L-PAMiD | Unidentified CN 86 SEBNWBM | Unidentified CN 86 SEBNWBM | Unidentified CN S111241C |
| UHB L-PAMiD | HiSilicon T04323 | HiSilicon Hi6D51FTQB7M7M9 | Unidentified CN S112541A |
| MMB PAM | OnMicro OM9902-11 | HiSilicon Hi6D05GLCV100001 | OnMicro OM9902-11 |

Evolution of the Mid-Band/High-Band RF Front End
One of the standout components in the Pura 70 Ultra is the MHB L-PAMiD, marked as 2D6BYSE21. This module, which was first introduced in the Mate 60, represents an evolution in Huawei’s RF design. Although it shares a similar architecture with the Mate 60 Pro’s S111341A module, it contains entirely unique die configurations, indicating continuous refinement by Huawei.
These components, although labeled as “unidentified” due to the lack of clear manufacturer markings, underscore Huawei's strategy to insulate its supply chain from external influences by relying on domestically sourced components.
Dual Satellite Communication: A Technical Breakthrough
The Pura 70 Ultra also features advanced dual satellite communication capabilities, supporting both BeiDou and Tiantong networks. This is achieved through a combination of the CETC MSC06A MSS SoC and the HiSilicon Hi1105GFCV120 connectivity SoC, supplemented by external components. This setup is largely consistent with what we observed in the Mate 60 Pro+, although the BeiDou communication setup in the Pura 70 Ultra uses slightly different hardware, reflecting Huawei's commitment to optimizing performance.
Detailed RF Transceiver Analysis
Our detailed analysis of the RF transceivers in the Pura 70 Ultra and Mate 60 series highlights Huawei’s ongoing efforts to refine its radio designs. The Pura 70 Ultra uses the HiSilicon T303263F1 transceiver, closely related to the FFY6633F1 found in the Mate 60 Pro. This choice of transceiver underscores Huawei's focus on optimizing 5G performance across its smartphone lineup.
