Spacecraft bus solutions for satellite system design

Rad hard electronics for reliable mission lifetime performance of satellite bus products and platforms

nobutton

Overview

Satellite bus platforms, also known as spacecraft buses, are structural frameworks providing infrastructure for payloads, subsystems, and communication, including RF microwave systems. They integrate power systems, often using rad hard DC-DC converters for efficiency. Relying on rad hard power MOSFETs, they ensure reliable attitude control and data processing, keeping the entire platform operational under extreme space conditions.

Benefits

  • Global certified HiRel facilities
  • DLA and ESA qualified solutions
  • Broad rad hard portfolio
  • COTS+ extended screening
  • Longevity programs
  • RF foundry services

About

Designing high-reliability satellite bus systems

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.
