Platforms

Amplification and cooling innovation as a platform.

GhostLink is a drop-in amplifier platform that amplifies and does nothing else. CryoShield is a nanomaterial that moves heat out of components and housings faster than copper. Independently, each lifts a hard constraint. Together they put multi-kilowatt, filterless RF into form factors legacy designs cannot reach.

On the bench

The claims, on instruments.

Linearity, pulse edges and polarization switching are the three things people ask us to prove first. These are the measurements we show them.

Spectrum analyser trace of a two-tone test showing intermodulation products
Two-tone spectrumThird-order intermodulation products driven down to levels as low as −91 dBc, so co-sited emitters do not contaminate each other.

Nanosecond pulsingA 90 ns RF burst with sharp rise and fall. Zero droop, no ringing, timings below a nanosecond on pulse products.

Polarization switchingNear-instant horizontal to vertical switching inside a waveform, which is what makes 3D and polarimetric modes possible.
Cool to the core

CryoShield™ cooling.

CryoShield is a non-toxic nanoparticle paste and powder. Put it directly on components, on housings, or use it as an additive in an immersion loop. No system redesign is required, so the thermal headroom shows up in hardware you have already built and already qualified.

How you spend that headroom is your call. Shrink the component, raise the output, ruggedize the part, or pack more of them into the same volume.

GPU overclocking figures are from synthetic testing. Dissipation in immersive cooling environments compounds beyond the air-cooled figure.

Power density

1.5× to 2.5× the power in 20–50% less rack.

The best-in-class competitor models used by SOCOM, BAE and Lockheed put 2 kW in an 8U chassis, 1 kW in 5U, and 500 W in 3U. The THEIA family covers all three of those points in 4U, and beats them on output at every one.
