12. Linear power amplifiers are used
to raise the power level of Low Level AM and SSB Signals.
13. A Mosfet power amplifier is used to increase the power level of an FM signal.
14. Linear power amplifier operate class A,B, and AB
15. A class A transistor power amplifier has an efficiency of 50 percent. The output power is 27W. The power dissipated in the transistor is 13.5 W
16. Class A amplifier conduct for 360 degrees of a sine wave input.
17. True or false. With no input, a class B amplifier does not conduct. FALSE
18. Class B RF power amplifiers normally used a(n) Broadband configuration.
19. A class C amplifier conducts for approximatly 90 degrees to 150 degrees of the input signal.
20. In a class C amplifier, collector current flows in the form of positive pulses.
