All RF Cafe quizzes would make perfect 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.Some of these books used in quizzes
are available as prizes in the monthly
RF Cafe Giveaway
Note: Many answers contain passages quoted from the text.

1. a) Right-hand rule.
See this RF Cafe
Labs experiment that proves the claim.
2. b) Lissajous waveform (lē'-su-zhOO").
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
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
