Acronyms & Abbreviations from the NIST Website

NIST - RF CafeHere is a convenient reproduction of the list of acronyms and abbreviations from the NIST website. It contains a lot of terms that are specific to the work they do along with commonly used terms. With the well-known propensity the government has for generating creative acronyms, this will help to decipher their clever schemes.

This list is provided as a reference for the NIST Physics Laboratory's Technical Activities publication. It is not intended as a comprehensive list in the area of physics.

About RF Cafe

Kirt Blattenberger - RF Cafe WebmasterCopyright
1996 - 2022
Kirt Blattenberger,

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
