RFMW, Ltd. announces a general educational White Paper from XMA Corporation for colleges, universities and commercial research of microwave designs and products at cryogenic temperatures. XMAs –CRYO attenuators and terminations are designed using resistive circuit materials with low TCR/TCA that will not super-conduct, even at temperatures nearing zero degrees Kelvin. The White Paper titled “Cryogenic Passive Attenuator” is available for download and provides an overview of the challenges of cryogenic research as well as XMA solutions for these temperature extremes. As their franchised distributor, RFMW supports specification and selection of both standard and –CRYO XMA components for production, test and a multitude of various applications.
