Abstract :
To improve power efficiency in a transmitter, a novel method is proposed, this being an uneven multi-level linear amplifier with a nonlinear component (UMLINC). Compared to a normal multi-level LINC (MLINC), the UMLINC employs a new uneven multi-level signal component separator (UMSCS) that significantly improves transmitter efficiency.
