Huawei Mate 50 series was released last year with support for satellite communication. However, the phones could only send messages through satellite and not make any calls. Huawei is now developing the Mate 60 series, which is also expected to have satellite connectivity. But the upcoming phones might even support voice calling thanks to new power amplifier chips.

The Huawei Mate 60 series is expected to have power amplifier (PA) chips made by Chinese chipmakers. These PA chips are specifically designed for the Tiantong-1 satellite mobile communication system. The satellite system can be used for voice communication, image transmission, precise positioning, and data reporting.

PA chips play a critical role in devices that use these satellite features. They are currently integrated into Huawei’s Mate X3 and P60 series, both of which support two-way satellite communication via SMS. These chips amplify the high-frequency signal generated by the communication integrated circuit (RF-IC) to the required output level and supply it to an antenna. This amplification process is essential for enabling effective satellite communication, including voice calls.

The PA chips rumored to be integrated into the Huawei Mate 60 series are allegedly not manufactured by Huawei; instead, the company has entrusted this responsibility to an undisclosed Chinese chipmaker. While it’s not confirmed at this point, the inclusion of these chips suggests that Huawei Mate 60 smartphones might support voice calling via satellite.

If this turns out to be accurate, it would mark the first instance of voice calling through satellite connectivity on a smartphone. To provide some context, Apple’s iPhone 14 series only supports emergency SOS calls through satellite.

Satellite connectivity on phones is an emerging technology and brands are rushing to implement this on their phones. If you’d like to learn more about it, we’ve just the explainer for you.
