IEEE 287.1-2021

The scope of this standard is to specify coaxial connectors for precision electrical measurements for use at radio frequency (RF), microwave, and millimeter-wave frequencies. Current state-of-the-art coaxial connectors are covered by the standard.

The purpose of this standard is to present minimum performance requirements for those precision connectors used at RF, microwave, and millimeter-wave frequencies. It introduces the performance requirements needed to standardize precision hermaphroditic and pin and socket type connectors and displays specification values from individual connector types in a connector summary table. This standard embodies the general requirements and definitions for all connector types covered by the standard, and for ease of use, separates the “detail specifications” information for each connector type for standardization into separate annexes. The previous version of this standard included 14 mm, 7 mm, Type-N (50 ?), 3.5 mm, 2.92 mm, 2.4 mm, 1.85 mm, and 1 mm connector sizes; the following connector sizes are being added to this version of the standard: 7-16, 4.3-10, Type-N (75 ?), 1.35 mm, and 0.8 mm.

New IEEE Standard - Active. The IEEE 287 series of documents presents the combined efforts of IEEE P287 Working Group that reflect the knowledge and experience of leading specialists in the development and measurement of precision coaxial connectors for RF, microwave, and millimeter-wave frequencies. It presents minimum performance requirements to standardize both hermaphroditic and pin and socket-type connectors (IEEE Std 287.1-2021, this document). It provides recommended electrical and mechanical test procedures for Instrument Grade and Metrology Grade precision connectors (IEEE Std 287.2-2021). Recommended reference procedures including connector effects, connector care and cleaning, connector repeatability and reproducibility test procedures, and a color code for connectors are detailed in the third part of the series (IEEE Std 287.3- 2021). A bibliography provides a list of pertinent references for measurement techniques used in determining electrical, mechanical, and dimensional parameters for coaxial connectors.
