Patent ID: 7746175

Claim:
An RF power amplifier, comprising: an RF input connection; an RF output connection; at least three sub-amplifier modules; a plurality of input paths electrically connecting each of the sub-amplifier modules to the input connection, wherein at least a portion of each of the plurality of input paths collectively and substantially define an input path plane; and a plurality of output paths electrically connecting each of the sub-amplifier modules to the output connection, wherein at least a portion of each of the plurality of output paths collectively and substantially define an output path plane, wherein at least one of: A) the paths of the plurality of input paths are electrically substantially identical; and B) the paths of the plurality of output paths are electrically substantially identical, wherein at least one of: A) the input connection is substantially parallel to the input path plane; and B) the output connection is substantially parallel to the output path plane, and wherein the input and output paths collectively further comprise at least one of: A) an input path section common to more than one of the input paths and to fewer than all of the input paths; and B) an output path section common to more than one of the output paths and to fewer than all of the output paths.
