RU1 · Radio Unit 1

Mission-critical connectivity, reinvented.

RU1 is a pocket-sized millimetre-wave radio that creates secure, gigabit-speed point-to-point links in minutes — on a tripod, mast, vehicle or drone — with no fiber runs and no towers.3

Built on TERASi’s AirCore™ technology, RU1 combines a lightweight, rapid-deploy design with low probability of intercept and detection (LPI/LPD), anti-jamming resilience and energy efficiency. Its directional beam keeps communications focused.2

Why directional mmWave

Broad signals announce themselves. A narrow beam doesn’t.

Current commercial and military solutions are largely omnidirectional and operate in a small range of frequencies.4 As TERASi puts it: extensive footprints, broad signals and regular patterns shout vulnerabilities.6

  • Focused energy. RU1 operates above 60 GHz with a highly directional beam, so energy goes where the link is — not across the landscape.3
  • Smaller footprint. Low probability of intercept and detection (LPI/LPD) and anti-jamming resilience by design.2
  • Fiber-class capacity. Millimetre-wave spectrum supports full-duplex, gigabit-speed links.6

Applications

Where infrastructure is missing, destroyed or too slow.

Technology · AirCore™

Waveguide performance, without the bulk.

At millimetre-wave frequencies the bottleneck isn’t only the chip. Losses in passive components — antennas, filters, interconnects — limit overall system efficiency. AirCore™ is TERASi’s patented, wafer-scale silicon-micromachining platform: waveguide-class performance without the bulk of conventional waveguide technology14, integrated with active chips in a single system-in-package.11

Layer

AirCore™ passives

Silicon-micromachined, waveguide-class antennas and filters. At high frequencies, losses in passive components limit system efficiency — this is the layer AirCore™ attacks.14

In-house design, manufacturing and test.1 The wafer-scale AirCore™ platform replaces manual processes with full automation13, and SiP assemblies are verified with extreme-resolution, sub-micron X-ray imaging.15

Beyond RU1: SATCOM and 6G

AirCore™ also underpins ESA-backed W-band active planar antennas for satellite communication17 and Eurostars-funded D-band system-in-package work with IHP and IAF.12
