NewSpace companies want trusted microwave/RF assemblies that meet stringent industry requirements for use in smaller, lower-cost launch vehicles and constellations of cube satellites. So they need assemblies in low-mass designs at a reasonable price that can be delivered quickly and re-used over many launch cycles and short missions. Not an easy task for cable manufacturers.

At Gore, we can help you navigate microwave/RF assembly requirements for NewSpace applications. We combine decades of extensive materials expertise and proven traditional spaceflight heritage to offer readily-available, cost-effective and reliable solutions. We’ve even completed thorough evaluation and qualification testing, so you don’t have to.


GORE Spaceflight Microwave/RF Assemblies are proven to deliver high-quality signal transmission with low insertion loss at frequencies ranging from DC to 40 GHz. They’re built precisely for optimal performance in high-frequency and high-density applications.

Our assemblies have been proven to resist the most extreme conditions they experience during complicated launch sequences and challenging low and medium earth orbit environments. They operate reliably in extreme temperatures and are resistant to repeated vibration, shock, radiation and atomic oxygen.

We have a thorough understanding of products operating in space and our customers’ needs for NewSpace applications. We’ve developed appropriately scoped NewSpace test procedures in line with existing ESA (European Space Agency) and NASA (National Aeronautics and Space Administration) specifications. So our microwave/RF assemblies are qualified according to NASA Level 2, ESA Class 2, and TRL 6+.


We offer several assembly types with small diameter sizes ranging from 2.0 mm (0.085 in) to 4.8 mm (0.190 in) in highly flexible, low-mass coaxial formats to meet specific application needs. We also offer a variety of connector variants — including SMA, SMP, SMPM, 2.92 mm, and TNCA — engineered to complement the performance of each assembly type, minimizing loss and reflection.

The bottom line is that we can help you overcome NewSpace challenges. We can provide qualified, reliable solutions that are low mass for more payload and can be re-used over multiple launches and missions. We can also manufacture and deliver GORE Spaceflight Microwave/RF Assemblies quickly to meet challenging program schedules at affordable prices you’ll appreciate.
