摘要：
Pre-distorters implemented at circuit level using series diodes have a high loss. The method presented here combines source/load second harmonic control with a parallel connected varactor diode. A reduction of 15dB in the spectral regrowth at 1.9GHz is achieved with a low loss of 2dB due to the varactor diode.
