Satellite Communication Chips: Strengthening the Core of Aerospace Connectivity, Empowering the New Space Era
In the ‘New Space’ era, characterised by the rapid development of commercial space activities, satellite communication chips must meet requirements for high reliability, radiation resistance, low power consumption and miniaturisation in extreme environments. Mingjiada Electronics has strategically positioned itself to cover the full spectrum of satellite communication chips, encompassing satellite navigation (GNSS) RF front-end, on-board storage, signal processing and ground station support chips. We are a key supplier of products from brands such as Infineon, TI, ADI and Xilinx, providing core support for low-Earth orbit satellite constellations, high-precision navigation equipment and ground communication terminals.

I. Satellite Communication Chips
1. Satellite Navigation (GNSS) RF Front-End Chips: Focusing on signal acquisition and amplification, the core models are represented by Infineon’s silicon-germanium process products, which feature high sensitivity and low noise characteristics, making them perfectly suited for mainstream global navigation systems.
- Infineon BGA524N6: A dedicated low-noise amplifier (LNA) for the core GNSS frequency bands, covering the 1550 MHz to 1615 MHz range. It features an ultra-low noise figure of 0.55 dB and high gain of 19.6 dB, enabling efficient amplification of faint satellite signals from tens of thousands of kilometres away and significantly enhancing the positioning accuracy of receivers in complex environments such as urban canyons.
2. Space-grade radiation-hardened memory chips: Designed for harsh space environments such as vacuum, extreme temperature fluctuations and cosmic radiation, with core components supplied by Infineon’s dedicated memory series, ensuring secure in-orbit data storage and high-speed transmission for satellites.
- Infineon FRAM series (Ferroelectric Random Access Memory): Boasting excellent Total Ionising Dose (TID) resistance, it supports a military-grade wide temperature range from -55°C to +125°C. Its low-power characteristics meet the long-endurance requirements of satellites, and it retains data without the need for a backup power supply, making it suitable for applications such as on-board data caching and instruction storage.
- Infineon pSRAM Series (Pseudo-Static Random Access Memory): Combining the high density of DRAM with the ease of use of SRAM, its high throughput is suited to high-speed data stream processing in satellite communications, whilst its radiation-hardened design ensures stable in-orbit operation, making it the core storage component for on-board signal processing modules.

II. Wireless Connectivity Chips
Short-range wireless connectivity chips (Wi-Fi/Bluetooth)
Focusing on high-speed transmission and device interconnection over short distances, core suppliers include HiSilicon, Broadcom, Espressif and Nordic, covering Wi-Fi 6/7 and Bluetooth 5.0 and above, catering to both consumer and industrial applications.
1. Wi-Fi Chips and Front-End Modules
- Qualcomm QCA6391: A Wi-Fi 6 + Bluetooth 5.1 combo chip supporting high-speed transmission and multi-device connectivity. Its low-power design is suitable for portable devices and is widely used in smart home systems, wearable devices, and in-vehicle entertainment systems.
- Broadcom CYW89650CWBG: An automotive-grade Wi-Fi 6 chip compliant with the AEC-Q100 automotive standard, featuring interference resistance and high stability. It is suitable for in-vehicle infotainment systems and connected vehicle terminals, supporting high-speed networking and device interconnectivity.
- QPF4259TR13: A high-power Wi-Fi 7 front-end module that integrates amplification, filtering and switching functions, simplifying system design whilst enhancing wireless signal coverage and transmission stability. It is suitable for high-end routers, industrial IoT gateways and similar devices.
- Espressif ESP32 Series: Wi-Fi/Bluetooth dual-mode chips, featuring high integration and low power consumption. They support multiple IoT protocols and offer outstanding value for money, finding widespread application in smart sensors, smart home devices, and wireless monitoring terminals.
2. Bluetooth Chips and SoCs
- Nordic NRF52840: A Bluetooth 5.2 SoC offering low power consumption and high data rates, with support for BLE Mesh networking. Suitable for wearables, smart home devices and industrial sensors, it boasts robust anti-interference capabilities.
- Hengxuan BES2700: Automotive-grade Bluetooth audio chip supporting Bluetooth 5.4 and LE Audio technology, featuring AI noise cancellation. Suitable for in-car audio systems, wireless headphones and similar products, enhancing audio transmission quality.
- NRF21540-QDAA-R7: A multi-protocol front-end module supporting Bluetooth, BLE, Thread and Zigbee. Highly integrated, it is compatible with multi-protocol IoT devices, simplifying interconnection design across multiple scenarios.
