Engineering Education Bulletin Boards, Tutorials, & Courses Websites - RF CafeIn good times and bad, keeping your technical skills honed is essential to advancement and even survival. There is a lot of competition for your position. It is not a sign of paranoia to constantly watch your back for people looking for their own opportunities to advance. Engineering careers are getting to be more and more a game of survival of the fittest... and strongest.

Your best defense against aggressors is keeping abreast of new technology and engaging in college coursework, attending workshops and seminars, and participating in the online forums. Social networking on sites like LinkedIn help provide inroads for applying your skills.

The companies listed here provide exactly the types of services needed to help ensure your survival.

About RF Cafe

Kirt Blattenberger - RF Cafe Webmaster

Copyright: 1996 - 2024


    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 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...
