RF Filters
From enabling global communication networks to monitoring climate change and supporting national security, the importance of satellites cannot be overstated. Designing these sophisticated machines to operate in the harsh operating environment of space however, poses a unique set of engineering challenges which simulation can help to overcome.
RF Filters for PCBs
Electronic / electrical systems utilise filters to selectively isolate desirable frequencies and eliminate undesirable frequencies. For example tunning to a desirable radio station or television channel requires selectively filtering the frequencies in the desired radio channel.
Simulation can provide automated design, synthesis and optimisation of RF, microwave and digital filters in an efficient and straightforward process. Specialised tools for RF Filter simulation can automatically set up filter analysis and optimisation in the Ansys HFSS electromagnetic simulation environment.
Satellite with Solar Panel Modal Simulation
Solar Panel Assemblies
- Must deploy reliably, with opening sequences controlled
- Excessive displacement from attitude control events must be controlled
- Withstand thermal cycle effects during lifecycle
- Withstand shock/impact loads during launch
- Understand system modes
Solar Panel Deployment
Surviving the Launch – PCB
When a satellite is attached to a rocket and launched into space, it experiences violent broadband vibration caused by rocket motors. These vibrations can cause PCB and electronic component failures in the satellite payload, rendering the satellite unfit for purpose once it gets to its orbit.
Simulation enables a physics-based electronics reliability analysis to be performed. A design tool that provides fast and accurate life predictions for electronic hardware at the component, board and system levels allows the engineer to fix issues early sin the design process.
Recently LEAP ran a webinar demonstrating how Ansys can help avoid unexpected PCB failures due to thermal, mechanical, and/or electrical stressors which we have made available on our Electromagnetics blog. Watch the recording and read the summary here.
