RF & Microwave Magazine Article Archive - 2017

RF & Microwave Magazine Article Archive 2017 - RF CafeIf you are like me, you spend a lot of time reading articles from technical magazines. Sometimes I read the entire article, but usually I just scan the text for highlights and look at the schematics, block diagrams, and charts / graphs. Often, I want to go back and find an article but cannot recall where I saw it. A Google search will usually eventually reveal a hyperlink to the article, but a lot of times it takes a lot of digging. Since my key interests are not necessarily the same as RF Cafe visitors, an attempt will be made to catalog all of them. If there is a magazine not included here that you would like me to include in the list, please send me an e-mail and I will try to incorporate its articles, too.

About RF Cafe

Kirt Blattenberger - RF Cafe Webmaster

Webmaster:

    Kirt Blattenberger,

    BSEE - KB3UON

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 tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

All trademarks, copyrights, patents, and other rights of ownership to images and text used on the RF Cafe website are hereby acknowledged.
