摘要：

A new design approach for compact multiband transmitters, using a miniaturized outphasing power combiner is proposed. The technique is applied to design a dual-band (0.9/1.8 GHz) outphasing power amplifier with a fully integrated power combiner in 90-nm CMOS technology. Power losses in the combiner are minimized using high-Q slab inductors. The measured maximum output powers at 0.9 and 1.8 GHz are 24.3 and 22.7 dBm with maximum efficiencies of 51% and 34%, respectively.
