Abstract:
To produce digital baseband domain, it is important to consider the non-linear signals for linearization. We in this work have processed the second and fourth order linearization signals and processed the amplitude and phase. We used the modulate carrier second harmonic which is further utilized for amplifier transistor. We studied the effects of the proposed linearization method are evaluated on a single stage power amplifier for simulated QAM digitally modulated signal characterized with frequency spacing between spectral components up to 20 MHz for different
input power levels.
