| Abstract: | 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 15 dB in the spectral regrowth at 1.9 GHz is achieved with a low loss of 2 dB due to the varactor diode |
