CCEM.RF-S1.CL (GTRF/02-03): RF Power Measurements with 2.4 mm Connectors



Thomas P. Crowley, J Miall, J dereede, J. Furrer, A Michaud, E. Dressler, T Zhang, K. Shimaoka, Ji Hyun Kim


A supplementary comparison of RF power measurements using 2.4 mm connectors was performed at 9 national metrology laboratories. The traveling standards were two commercial thermoelectric sensors and an associated power meter. Measurements were made at eight frequencies between 2 and 50 GHz. This is the first comparison to make measurements above 26.5 GHz with coaxial connectors. All participant measurements agree with the reference values within their expanded uncertainty. The participants represent the United States, the United Kingdom, the Netherlands, Switzerland, Canada, South Africa, Australia, Japan, and South Korea. The pilot laboratory was the National Institute of Standards and Technology (NIST) of the United States
