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 in whole or in part 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").
 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
