General Knowledge
Answers to RF Cafe Quiz #13

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. Bonne chance, Viel Glück, がんばろう, buena suerte, удачи, in bocca al lupo, 행운을 빕니다, ádh mór, בהצלחה, lykke til, 祝你好運. Well, you know what I mean: Good luck!

Note: Some material based on books have quoted passages.

1. a) Right-hand rule.

See this RF Cafe Labs experiment that proves the claim.

2. b) Lissajous waveform (lē'-su-zhOO").

 Lissajous pattern on o-scope

Named after Jules Antoine Lissajous.

3. b) frā-nĕl'  -  that's right, it is NOT pronounced frĕz-nĕl'

4. a) Lowpass

Low frequencies easily pass through the series inductors and do not pass through the shunt capacitors.

5. b) 4

Each reactive component (2 inductors + 2 capacitors) creates a pole in the transfer function.

6. c) Microstrip

Microstrip uses a conductor running over top of a ground plane, with a dielectric in-between.

7. b) 90° H-Plane bend

The mnemonic used for waveguide is that an E-Plane bend curves along the narrow side (the "E"asy bend), and that a H-Plane bend curves along the wide side (the "H"ard bend). There is no such thing as a Maxwell bend.

8. c)  62 kΩ, ±10% = 3 (62 x 103 = 62 kΩ), Silver = ±10%

9. a) Tin whiskers

10. b)
