  • Abstract
    In this paper, an LDMOS class-AB balanced power amplifier with a 3-dB bandwidth of 800 MHz at a center frequency of 2 GHz is presented. To the best of the authors´ knowledge, this is the largest bandwidth reported so far at these frequencies in an LDMOS technology. 50 Watt output power, high efficiency, high linearity and input-and output-matching better than -10 dB have been achieved over this large frequency band. An advanced stability improvement is introduced in this paper.
