Mingjiada Electronics Supply Satellite Communication Chip, GNSS Navigation Chip

With the accelerated development of global low-Earth orbit satellite constellations, satellite communication technology is transcending the limitations of terrestrial networks, permeating diverse scenarios such as emergency response, ocean shipping, smart terminals, and aerospace. As the computational heart of satellite communication systems, core chips directly determine communication speeds, interference resistance, and device miniaturisation levels.

Shenzhen Mingjiada Electronics Co., Ltd. — with nearly three decades of specialisation in semiconductor chip supply — has established a comprehensive chip supply system covering the entire satellite communications spectrum through deep collaboration with over 500 globally renowned manufacturers. This system encompasses both international first-tier brands and domestic core brands, offering one-stop supply services ranging from satellite-borne chips and RF components to terminal communication chips. This empowers clients to seize new opportunities within the aerospace information industry.

1. STMicroelectronics
As a core chip supplier for Starlink satellites and ground terminals, STMicroelectronics' satellite communication portfolio encompasses three key categories: satellite-borne microcontrollers, RF chips, and GNSS navigation chips. Leveraging high integration and reliability, these solutions are widely deployed in low-Earth orbit satellite constellations and satellite navigation terminals.
Mingjiada Electronics supplies the following models:
- STM32 series microcontrollers: STM32H743VGT6 and STM32L496VGT6. Featuring high radiation resistance design to withstand extreme space environments, these integrate multiple communication interfaces supporting satellite attitude control and data transmission. With cumulative shipments exceeding 5 billion units, they serve as core control chips for Starlink satellites.
- GNSS navigation chips: STA8100 and STA8090, supporting multi-system joint positioning across GPS, BeiDou, Galileo, and GLONASS with centimetre-level positioning accuracy and nanosecond-level timing precision. Suitable for autonomous driving, precision agriculture, and wearable devices, these chips also feature low power consumption to extend terminal battery life;
- BiCMOS RF antenna chip: Specifically engineered for Starlink terminals, supporting Ku/Ka-band signal transmission and reception. Features Doppler shift resistance to compensate for signal attenuation caused by high-speed satellite movement, ensuring stable ground-to-satellite connectivity.

2. Qorvo
Qorvo is a global leader in RF chip supply, with satellite communication chips characterised by high integration and high power capabilities. It commands over 80% of the global phased array MMIC chip market share. Mingjiada Electronics has been a long-term supplier of its core products including beamformers and RF amplifiers. Key models comprise:
- Beamformers: AWMF-0221, AWMF-0146, AWMF-0147, AWMF-0197, AWMF-0198. These belong to the high-performance active antenna IC portfolio, covering Ku, K, Ka, and millimetre wave bands. They offer high linearity, flexible polarisation control, and compact packaging advantages, serving as core components for rapid beamforming in active phased array systems. They are suitable for high-end applications such as satellite communications and aerospace.
- High-power MMIC chips: QPA2710, QPA2720. Utilising GaN technology, these offer high power density and robust interference resistance. They support mobile-to-satellite direct communication scenarios such as AST SpaceMobile, providing stable signal amplification for large phased array antennas.

3. Qualcomm
Qualcomm possesses extensive expertise in satellite terminal communication chips, particularly leading in mobile-to-satellite direct communication technology. Mingjiada Electronics supplies its Snapdragon Satellite satellite communication solutions and terminal baseband chips, with core models including:
- Snapdragon Satellite Baseband Chips: X70 and X80, supporting 3GPP NTN standards. These are tailored for direct mobile-to-low-Earth-orbit satellite connectivity, enabling voice, messaging, and low-speed data transmission without requiring customised terminals. They are already deployed in multiple flagship smartphones.
- Satellite RF front-end chips: QPM5675 and QPM5676, integrating components such as filters and amplifiers. These support Ku/Ka-band signal transmission and reception with low-power characteristics, suitable for portable satellite hotspots and in-vehicle satellite terminals;
- Automotive-grade satellite communication chip: SA8155P. Supports dual-mode satellite and cellular communication, tailored for integrated vehicle-to-everything (V2X) communication scenarios, providing uninterrupted connectivity assurance for intelligent driving.
