Minimizing Outgassing & Multipaction Risks In RF Filters For Space

Designing RF filters for space missions requires engineering precision that accounts for the harsh realities of orbit. Unlike terrestrial systems, spaceborne filters must operate reliably amid rapid temperature fluctuations, high radiation levels, and the hard vacuum of space—conditions that amplify two critical risks: outgassing and multipaction.

Outgassing occurs when volatile compounds within filter materials or adhesives are released in vacuum, potentially contaminating sensitive payload components or optics and degrading performance. Multipaction, on the other hand, arises when free electrons accumulate and avalanche within the filter cavity, leading to electrical breakdown, signal distortion, or even catastrophic component failure.

This on-demand webinar delivers a comprehensive look at how engineers can identify, prevent, and manage these challenges throughout the product lifecycle. Attendees will gain actionable insights on material selection, structural design techniques, and validation testing aligned with modern industry standards. Real-world examples will highlight how proper screening and design discipline can reduce risks and extend mission life.

In addition, the session explores how to balance the trade-offs between commercial-off-the-shelf (COTS) and custom RF filter solutions for space programs—considering performance, qualification requirements, and cost implications.
