Return to RF Cafe Quiz #13
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.

Note: Many answers contain passages quoted in whole or in part from the text.
1. a) Right-hand rule.
See this RF Cafe
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
