TITLE: Type N and 2.4 mm Power Transfer Standards

Requesting Laboratory / Division / Group:

Communications Technology Laboratory Radio Frequency Technology Division Guided Wave Electromagnetics Group (672.01)

General Statement of Need:

The Communications Technology Laboratory (CTL) at the National Institute of Standards and Technology (NIST) enables science and industry by providing essential measurement methods, instrumentation, and standards to support all phases of communications technology development, from fundamental characterization and discovery to production.

To support research and measurement services in radio frequency and microwave power, the Radio Frequency Technology Division in CTL requires Type N and 2.4 mm power transfer standards that are compatible with microcalorimeters. These items are being acquired as part of an agreement with the Navy Primary Standards Laboratory.
