Abstract
A multi-stage Radio Frequency (RF) power amplifier is presented herein. According to one embodiment, the amplifier comprises: a first amplification stage configured to amplify an input signal to provide a first output signal having a phase distortion; a second amplification stage having an input and configured to amplify the first output signal that is received at the input to provide a second output signal, wherein the second output signal has a carrier frequency (F) modulated by a signal content (S) having a signal content bandwidth (F); and a resonant circuit comprising an inductor and a capacitor and having a resonant frequency (F), the resonant circuit coupled to the input of the second amplification stage and compensating for the phase distortion caused by the first amplification stage at frequencies within the signal content bandwidth F, wherein the resonant frequency Fis less than the signal content bandwidth F.
