Abstract
This paper describes the design methodology and presents measured results for a 5GHz Chireix out-phasing power amplifier. The outputs of two high efficiency amplifiers operating in class F are combined using a lossless combiner. A novel implementation of the class F output tuning networks and combiner using bond wires is also described. To our knowledge, this is the most efficient 802.11a amplifier ever reported.
