Cryogenic Low Noise Amplifiers

Low Noise Factory, Sweden, has spent decades building the amplifiers that the world’s most demanding scientific applications rely on: quantum computers, space probes, and radio telescopes. Globetek brings that technology exclusively to India.

OUR PRINCIPALS

Exclusive Partner of Low Noise Factory, Sweden

Low Noise Factory builds the amplifiers that push the boundaries of what’s measurable: cryogenic LNAs, room temperature amplifiers, and isolators covering 0.2 to 96 GHz with the industry’s lowest noise temperature of 1.1K. Every unit tested at 4K before delivery.

THE BIG WHY

Why Choose Our Amplifiers

There are very few people in India who understand cryogenic LNA applications deeply. We are one of them. When you reach us, you get decades of experience specifying and supporting these systems for India’s most advanced research institutions.

  • Extreme Reliability
    01 Extreme Reliability
    Built to withstand the most demanding conditions while maintaining consistent performance across thousands of cycles. Every cryogenic LNA is tested at 4K before delivery, because in quantum computing and space research, performance must be proven and not assumed.
  • Rigorous Testing
    02 Rigorous Testing
    Every cryogenic amplifier tested at 4K before delivery. Sample units undergo 100+ cool-down cycles to near absolute zero, ensuring reliability in the most extreme operating environments on Earth and beyond.
  • Nanometre Precision
    03 Nanometre Precision
    Transistors produced in world-class cleanrooms with precision measured in nanometres and single layers of atoms, using electron beam and laser lithography. Gold-plated OFHC copper body minimises thermal loss at cryogenic temperatures.
APPLICATIONS

Where Globetek meets the industry

Quantum Computing

Quantum Computing

Qubit readout tolerates almost no added noise, a fraction of a kelvin corrupts state measurement.

Low Noise Factory’s cryogenic LNAs, with noise temperatures as low as 1.5K, ensure reliable readout.

Space Research

Space Research

Low Noise Factory’s cryogenic LNAs have helped receive signals from Voyager 1, the most distant object.

For satellite ground stations and deep space networks, their amplifiers detect the weakest signals possible.

Radio Astronomy

Radio Astronomy

Radio telescopes amplify signals so faint that any noise introduced by the amplifier overwhelms science.

Low Noise Factory’s cryogenic LNAs, covering 0.2 to 96 GHz at 1.5K, suit sensitive receiver systems.

Physics Research

Physics Research

Dilution refrigerators and low-temperature physics research demand amplifiers reliable near absolute zero, across cycles.

Low Noise Factory’s LNAs undergo 100+ cool-down cycles; India’s quantum institutions get that reliability, locally supported.

Quantum Communication

Quantum Communication

Quantum communication systems require signal amplification that preserves quantum states without compromising signal integrity.

Low Noise Factory’s cryogenic and room temperature LNAs provide the ultra-low noise amplification quantum networks demand.
