A modular, software-defined RF Power Processing Unit that takes power electronics off your critical path — without the cost, mass, or thermal penalty of legacy hardware.
The Drag Barrier
No One Is Solving
<400 km
The altitude where imaging resolution and signal latency peak — and where atmospheric drag is unforgiving.
Very Low Earth Orbit delivers unmatched imaging resolution and near-zero signal latency. But the residual atmosphere creates aerodynamic drag that kills satellites in weeks or even days. Traditional Power Processing Units compound the problem — bulky, thermally inefficient designs add mass that accelerates orbital decay. The industry has been patching the problem. MHz Labs eliminates it.
<400 km
VLEO Altitude
Where imaging resolution, signal latency, and link budgets reach their peak — and where atmospheric drag is unforgiving.
~3 months
Avg. Satellite Lifespan
Without active drag compensation and efficient propulsion, VLEO satellites de-orbit in weeks to months — not years.
40–60%
PPU Thermal Loss
Legacy silicon-based PPUs dissipate nearly half their power as heat, demanding heavier shielding and larger radiators on every mission.

01 — GaN Technology
3× the power density. Half the mass.
High Power Density,
Radical Miniaturization
Gallium Nitride semiconductor substrates operate at higher voltages and temperatures than silicon, delivering 3× the power density. Less mass. Less volume. More margin for your propulsion system.
02 — Software-Defined
Plasma fluctuates. Your PPU doesn't.
Real-Time Dynamic
Impedance Matching
Firmware-controlled matching network adjusts in microseconds — maintaining peak efficiency across the full operational envelope. No manual tuning. No re-qualification.
03 — High Efficiency
>90% efficient. Smaller radiators. Longer missions.
>90% Conversion
Efficiency
Our proprietary power algorithm minimises thermal dissipation to near-zero. Thermal load on your satellite bus drops dramatically — smaller radiators, lighter structure, longer mission life.
04 — European Sovereignty
Full European supply chain. Zero restrictions.
No Export Restrictions.
No Compliance Bottlenecks.
Designed and manufactured in Spain under full European supply chain oversight. Zero ITAR constraints — streamlined procurement for ESA programs, allied agencies, and commercial operators.
