By: Khoi Tran In the unforgiving environment of space, RF coaxial interconnects must meet rigorous demands for performance, durability, and consistency. From extreme temperature fluctuations to high levels of radiation and vibration, these components are essential to mission success. In our latest article for Microwave Journal, Pasternack explores the essential design and material considerations for building space-grade RF coaxial interconnects, including insulation stability, shielding effectiveness, and connector precision. The article also covers testing protocols such as thermal vacuum cycling and outgassing analysis, which are necessary to qualify components for launch and long-term orbital performance. Whether you’re developing satellite communications, deep-space probes, or defense-grade aerospace systems, understanding these requirements is vital for engineers tasked with building robust RF systems.
