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.

* Note: There is no 'dark' side of the moon since at any given time fully half of the moon is illuminated by the sun, in the same
            manner as half the Earth is illuminated, depending on its orientation toward the sun. The meaning of 'dark' as applied
            to the far side of the moon, which always faces away from Earth, can be taken as per Merriam-Webster:

              4  a :  not clear to the understanding
                  b :  not known or explored because of remoteness

Note: These historical tidbits have been collected from various sources, mostly on the Internet. As detailed in this article, there is a lot of wrong information that is repeated hundreds of times because most websites do not validate with authoritative sources. On RF Cafe, events with hyperlinks have been verified.
Please submit significant historical events and dates for inclusion in these lists. I will be glad to include your name and birthday. Please do not submit your death date ;-) A couple years ago, I began commemorating the birthdays of notable people and events with special RF Cafe logos. Where available, I like to use images from postage stamps from the country where the person or event occurred.
