RF POWER AMPLIFIERS TECHNICAL REFERENCE MATERIAL
Class C operation
Class C Amplifiers are not DC forward biased. Collector current, IC, flows over significantly less
than 50% of the RF input cycle.
Class C amplifiers have a very limited dynamic range (0 to 6 dB) and have a tendency to snap off if the RF input signal is reduced below the rated level.
Class C Advantages:
Multikilowatt Pulse Output Power
CW, FM, Phase and Pulse Amplification
Class C Disadvantages:
Poor Dynamic Range
Cannot Support AM Signals
