RFMW

Cryogenic Passive Products
XMA is committed to manufacturing and developing high quality products and high-tech solutions. XMA offers Attenuators and Terminations capable of performing at extremely low temperatures. These products have the ability to operate at 4° Kelvin or -269.15° Celsius, with great stability. The proprietary, thin film resistor deviates less than 2% from 50 Ohms. The components do not superconduct under extremely cold conditions.
   

Features and Benefits
