ENGINEERING ANSWER
Satellite communications boards can contain filters, converters, amplifiers and antenna feeds across different frequency bands. Material selection must follow the circuit’s electrical, thermal and environmental requirements.
What to decide before release
Separate ground-terminal needs from flight hardware qualification. Review loss and phase stability alongside assembly and long-term exposure. Use documented material and process evidence for any reliability requirement.
Checks to put in your design brief
- State the exact band and environment
- Review thermal and aging behavior
- Require relevant qualification evidence
Important distinction
No general laminate description proves that a finished board is space-qualified.
