The low-temperature non-magnetic attenuators, low-temperature non-magnetic loads, and low-temperature non-magnetic adapters developed are widely used in quantum computing. Core materials are self-researched and self-produced (adopting mature designs and processes from America), and the processing and production are completed in China.
Low Temperature Signal Conditioning
Stable RF performance near absolute zero.

Low Temperature Signal Conditioning solutions from INMET include coaxial and chip attenuators and terminations engineered for cryogenic and other low-temperature applications. These products help maintain RF performance where conventional resistive technologies can fail.Key benefits

Supports cryogenic, quantum computing, aerospace, and scientific research applications.
Provides temperature-stable operation down to 4 mK.
Includes coaxial and chip solutions for low-temperature signal paths.
Helps reduce thermal noise and support system stability in cryogenic environments.
Why it matters

Low Temperature Signal Conditioning gives engineers RF signal-path solutions for environments where standard components are not designed to operate reliably.
