Below are the answers key for Frenzel Self-test in Chapter 10: Microwave Techniques from the book COMMUNICATIONS ELECTRONICS by Louis E. Frenzel. Make sure to familiarize each and every questions to increase the chance of passing the ECE Board Exam.
1. 1
2. bandwidth or spectrum
3. more difficult to analyze; different measurement techniques; resistors, capacitors, and inductors act
like LCR circuits; conventional semiconductors do not work owing to internal capacitances and long
transit time; special, expensive vacuum tubes are used for power amplification; line-of-sight
transmission differences; excessive signal reflection and absorption
4. telephone, radar
5. television signal relay, space communications, radio telescopes, microwave heating
6. Federal Communications Commission
7. improved receiver selectivity, SSB, multiplexing, reduced FM deviation
8. internal capacitance, long transit time
9. LCR
10. 36, 3.6

20. H, E
21.TEO,1
22. transverse magnetic
23. cavity resonator
24. parallel resonant
25. tuned circuits, filters
26. resonant frequency
27. high capacitance, high inductance, long transit time
28. P-type silicon, tungsten whisker
29. Schottky barrier, or hot carrier
30. mixer
