Cryogenic Low Noise Amplifiers

PRODUCT CATEGORY

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.

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.
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.
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 Qubit readout chains

Space Research Satellite and deep space signal reception

Radio Astronomy Ultra-sensitive receiver systems

Physics Research Cryogenic experiments and dilution refrigerators

Quantum CommunicationLow-noise signal amplification

Quantum Computing

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

Low Noise Factory’s cryogenic LNAs, with noise temperatures as low as 1.5K, are the amplifiers quantum computing labs worldwide trust for reliable readout chain performance.

Space Research

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

For satellite ground stations, deep space communication networks, and space-based instrument chains, their amplifiers provide the sensitivity that makes detection of the weakest signals in the universe possible.

Radio Astronomy

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

Low Noise Factory’s cryogenic LNAs, covering 0.2 to 96 GHz with noise temperatures as low as 1.5K, are the amplifiers of choice for the world’s most sensitive receiver systems.

Physics Research

Dilution refrigerators, cryogenic experiments, and low-temperature physics research demand amplifiers that perform reliably at near absolute zero, across hundreds of thermal cycles.

Low Noise Factory’s cryogenic LNAs go through 100+ cool-down cycles during testing. India’s quantum research institutions and physics labs get that same reliability, with Globetek’s local application support.

Quantum Communication

Quantum communication systems require signal amplification that preserves quantum states. Any added noise compromises the integrity of the signal.

Low Noise Factory’s cryogenic and room temperature LNAs provide the ultra-low noise amplification that quantum key distribution and quantum network infrastructure demand.
