1.	RF amplifiers tend to be ____ amplifiers.(a) class A(b) class B(c) class C(d) class ABThe question was posed to me during a job interview.This interesting question is from RF and IF Processing Tradeoffs topic in division Technology Tradeoffs in Software Defined Radio of Cognitive Radio
Answer» The correct OPTION is (c) class C Explanation: RF amplifiers operate in saturated MODE (class C). It non-linearly DISTORTS the waveform. Class A, class B, and class AB are linear amplifiers. The output SIGNALS are linearly related to input signals.
