A modified linear amplification with nonlinear component (LINC) transmitter is presented using a novel power combination scheme.By using multiple LINC sections in parallel with a compact adaptive power combining network, the output power of power amplifiers can be boosted, together with obtaining higher efficiency over a large power back‐off region. Compared to existing designs, no gate bias adaptation is needed and efficiency can be further improved. © 2011 Wiley Periodicals, Inc.
