Parallel amplifier apparatus for wireless communication that shares the inside of the matching-use inductor

Parallel amplifying devices have a plurality of power amplifier having at least one output end and a plurality of driving amplifiers and a respective power amplifier with at least one input end having at least one output terminal and at least one input end of each drive amplifier can. In addition, the parallel amplifier may have a shared inductance device provides a common and matching between each of the output ends of the plurality of driving amplifiers and each of the input ends of said plurality of power amplifiers. These shared inductance dabayiseu may be a shared or a shared inductor transformer.
