Cryogenic Low Noise Amplifiers
Globetek brings you the world’s best Cryogenic Low Noise Amplifiers from Low Noise Factory, Sweden who have pioneered the development of these LNA’s with the Industry’s lowest noise temperature.
They design and produce the world’s best low noise microwave amplifiers. These amplifiers are used near absolute zero –cryogenic– temperatures for space exploration, quantum computing, radio astronomy, and for various ground-breaking scientific endeavours where extreme sensitivity is paramount. Our amplifiers help receive signals from the most distant man-made object from Earth, the Voyager 1 space probe, help read quantum states in the fastest quantum computers, and help make MRI scanners work in medical institutions.
The roughly 20-step manufacturing process requires meticulous attention to detail and thoroughness, and we have mastered both. Despite the invisibly small componentry, our amplifiers are built to withstand some of the most extreme of conditions.
Our transistors are produced in a world-class cleanroom. They are processed in about 20 steps using electron beam and laser lithography. Precision in our transistors is measured in nanometres and single layers of atoms, a level of accuracy that decides the quality of the end product.

Cryogenic Low Noise Amplifiers
Multiple Cryogenic LNA options from 0.2 to 96 Ghz with the industry’s lowest noise temperature of 1.1K All amplifiers we build for cryogenic use are tested at 4 K before being delivered to customers. Sample LNAs are handpicked to go through excruciating experiments such as being cooled down to near absolute zero.
100 times during a testing. After all, they have to perform well at 4 K not only once, but every single time.
Room Temperature Amplifiers
State of the art Industry’s best room temperature amplifiers from 4 Ghz to 115 Ghz. With noise temperature of 32k. Manufactured using InP HEMT technology, the LNA is packaged in a coaxial module using industry standard SMA connectors for the RF ports and Nano 4-pin polarized connector to provide the DC. All amplifiers are tested at 296 K and delivered with a test report.
Cryogenic Isolators and Cryogenic Circulators
Ultra-low insertion loss cryogenic isolators and circulators with various models is the 4 Ghz to 12Ghz range with an insertion loss of 0.17 dB. They have been designed from ground up to meet the strict requirements of ultra-low temperature physics research. The gold plated OFHC copper body ensures minimum loss and that this loss reaches the lowest possible temperature to minimize thermal noise. The cryogenic isolator and cryogenic circulator is packaged in a slim coaxial module using industry standard SMA connectors.
They are available in single, dual and triple junction configurations.
