Overview

Space bus platforms, also known as satellite buses, are the structural and functional frameworks upon which various space missions are built. They provide essential infrastructure and support systems for payloads, power, propulsion, communication, attitude control, and other necessary functions to keep the spacecraft operational. Satellite buses also handle a variety of tasks related to data acquisition, storage, processing, and transmission.

About

Mission requirements, such as payload type, mass, orbit, and duration, drive the design of satellite subsystems and spacecraft buses. Optimizing mass and volume distribution is key; a lighter platform carries more payload, enhancing mission efficiency.

Ensuring efficient satellite bus operation relies on the reliability of critical satellite power system components. Infineon’s HiRel solutions portfolio features rad hard power MOSFETs, ICs, and memories (and more) engineered for longevity under severe ionizing radiation. Our products are flight-proven across thousands of programs, supporting RF microwave systems and attitude control. Customers count on our high-reliability track record for long-term commitment to space exploration.

Infineon offers a differentiated portfolio of rad hard memories for extreme environments such as those found in space, aviation, defense, and other industries. Our extensive portfolio supports volatile and non-volatile memories with serial and parallel interfaces. Infineon’s high reliability memories adhere to the most stringent standards in the industry and are DLAM QML certified, meeting the reliability and lifecycle demands of aerospace and defense applications.

Infineon’s rad hard power electronics are used across the satellite bus and spacecraft bus to improve size, efficiency, and power density in satellite power system and PMAD architectures. Our portfolio includes rad hard and rad tolerant power MOSFETs,  ICs, rad hard GaN, solid state relays, synchronous rectifiers, and Schottkys designed for demanding satellite subsystems. Certified to ESA and DLA standards, these space-proven components are recognized globally for performance, reliability, product longevity, and established design heritage.

As a key supplier of discrete semiconductor devices for the high reliability community, Infineon has built an excellent reputation in space community for over 40 years. From silicon to backend and screening, Infineon’s RF capabilities include space-qualified silicon microwave transistors and foundry services.
