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 World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while typing up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...

U.S. Radio Frequency Allocations - 30 MHz to 300 GHz |
These are the United
States radio frequency allocations per the wall chart issued by RF Design magazine in 2005.
As with all
bureaucracies, the
FCC (Federal Communications Commission) rules are changed all the
time, so it behooves you to check the source for regulations on frequency allocations, power limits, modulation
techniques, etc., prior to planning any serious production design or implementation. The responsibility is
entirely yours to assure compliance.
Download the
2003 U.S. Frequency Allocation Chart
published by U.U. Department of Commerce.
Download the 2007 "Selected
U.S. Radio Frequency Allocations from 30 MHz to 300 GHz" wall chart PDF file from RF Design.
