General overview
Satellite communication systems are rapidly advancing to meet the increasing demand for global connectivity. Manufacturers face the challenge of building reliable, efficient, and scalable systems for Low Earth Orbit (LEO) satellites, user terminals, and ground stations that can operate under extreme environmental and performance-based constraints.
Infineon’s semiconductor portfolio offers a wide range of solutions to address these challenges at every level of the satellite communications ecosystem. With a focus on efficient power conversion, radiation tolerance, and high reliability, we provide designers with the tools and technologies necessary to create robust systems that meet the demands of both today and tomorrow.
LEO satellites
LEO satellites operate in harsh environmental conditions where radiation exposure, thermal management, and energy efficiency are critical design considerations. These satellites are typically smaller, require lower power budgets, and are produced in greater quantities compared to traditional Geostationary Orbit (GEO) systems.
Our semiconductor solutions help address these engineering challenges:
- Radiation Tolerance: Satellites are exposed to high levels of radiation that can degrade semiconductor performance. Our portfolio includes radiation-tolerant devices designed to withstand Total Ionizing Dose (TID) and Single Event Effects (SEE), ensuring stable operation throughout the mission lifecycle.
- Power Efficiency: Our technologies enable high-frequency power conversion with low losses, reducing the thermal footprint and increasing overall power efficiency. This is critical for lightweight, space-saving designs.
- Reliable Power Distribution: High-efficiency DC-DC converters provide robust power management for satellite subsystems, such as communication payloads, avionics, and propulsion systems.
User terminals
User terminals, also referred to as a satellite terminal or dish, allow users to access satellite-based services such as broadband internet, voice, and data communication. Manufacturers face the challenge of achieving compact, energy-efficient, and high-performance designs capable of operating in remote or off-grid environments.
Our portfolio addresses these requirements with:
- Efficient Power Conversion: Power management ICs and discrete components enable efficient energy distribution and conversion, helping reduce overall power consumption.
- Security: Hardware-based security solutions to protect data and maintain device integrity.
- Energy Storage: enables off-grid operation using solar power and batteries with efficient energy storage and reliable power delivery.
- Thermal Considerations: Our SiC and GaN solutions provide efficient switching and low power loss, helping reduce thermal load in compact, high-density designs.
