Abstract
A novel wide band high power recycling approach has been developed. The design is optimized for high efficiency, high isolation, and minimal number of ferrite cores. The combiner part includes an effective flux canceling circuitry to significantly improve its inter-modulation distortion performance, and the isolating resistors can be replaced by an efficient RF to DC conversion circuitry. The recycling combiner has been successfully fabricated, tested, and full performance evaluation have been carried out. This combiner allows portion of the wasted components of the signal to be reused by the power supply; thus the over all efficiency of the wide band outphasing power amplifier can be improved.
