Abstract
A design technique for dual-band multi-way Doherty power amplifier (PA) using dual-band networks is proposed in this paper. A T-network and a two-section line network are used to implement dual-band impedance transformer. Experimentally, the proposed PA achieves a power added efficiency (PAE) of 33% with 7dB back-off and 29% with 8 dB back-off from the saturated output power at 0.92 GHz and 1.99 GHz. Compared to other dual-band Doherty PAs, the back-off range of the proposed Doherty PA is much wider.
