Radio Frequency (RF) and microwave power measurements are widely used to support applications across space, defence, and communication. These precise measurements enable engineers to accurately characterise waveforms, components, circuits, and systems.
Taking this a step further, AIRTO member NPL and Keysight Technologies collaborated on a groundbreaking research project, exploring RF power at cryogenic temperatures. This resulted in the world’s first successful demonstration of a commercial RF power sensor operating at temperatures as low as 3 kelvin.
This not only marks a significant technological milestone, but it is a critical step forward in supporting quantum development and other applications that require cryogenic conditions. This breakthrough opens new possibilities for quantum technologies, where accurate RF power measurements at cryogenic temperatures are crucial.
