In GaN-on-Diamond, the hottest part of a transistor is brought to within tens of nanometers of synthetic diamond – the most thermally conductive material ever made by humans. The result is a dramatic reduction in the waste heat generated from the power amplifier, and therefore the entire satellite system; in the communications “base stations” of space, the RF power amplifier is typically responsible for the bulk of the power consumed and the heat generated. The cooler state of operation gives RF and satellite system designers a previously unattainable thermal envelope to

dramatically improve a satelliete’s communication bandwidth and energy efficiency while simultaneously shrinking the system’s size, weight, and operating costs.

At Akash, our vision is to enable the satellite industry to exploit these benefits, eventually producing terabit data rates and centimeter-range video resolution, for example. We envision new satellite services enabled by orders-of-magnitude increases in information density and access. We believe this vision will allow a rethinking of what is possible with satellite communications on Earth, between Earth and Deep Space, or, beyond that, to human colonies in Space. All of this can be enabled by an invention that allows us to “beat the heat” and reinvent satellite communications. Learn more…
