Abstract :
This paper introduces a 900 MHz distributed active transformer coupled outphasing power combiner. The distributed active transformer is applied as the impedance transformer and power combiner for the outphasing power amplifier. Compared to existing solutions, the new architecture owns the advantages of low loss and compact size. The proposed combiner is suitable for fully integrated RF outphasing power amplifier design.
