XMA Corporation has announced further developments of their high frequency CRYOGENIC product family of attenuators, adapters, and terminations, expanding performance parameters into the 4 Kelvin (-273.15°C) temperature range. They now offer a complete line of CRYOGENIC RF, coaxial passive components that range from DC to 50 GHz in frequency range using various industry standard connectors. The proprietary, thin ‑lm resistor deviates less than 2% from 50 Ohms. The components do not superconduct under extremely cold conditions.
Technical advancements with thin film design and fabrication at XMA, allows performance levels to reach new milestones with Millimeter and Microwave RF products. The future growth area for CRYOGENIC coaxial products is found in all frequency bands where severe environmental conditions mandate high performance levels, primarily for deep space, Magnetic Resource Imaging (MRI) and base communications transceivers located on commercial satellite platforms.
