RF Cafe Quiz #46

RF Engineering Quizzes - RF CafeAll RF Cafe quizzes make great fodder for employment interviews for technicians or engineers - particularly those who are fresh out of school or are relatively new to the work world. Come to think of it, they would make equally excellent study material for the same persons who are going to be interviewed for a job.

Click here for the complete list of RF Cafe Quizzes.

Note: Some material based on books have quoted passages.


Handbook of RF, Microwave, and Millimeter-Wave Components - RF Cafe Featured BookThis quiz is based on the information presented in Handbook of RF, Microwave, and Millimeter-Wave Components, by Sergey M. Smolskiy, Leonid A. Belov, and Victor N. Kochemasov.

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