Abstract
A radio frequency module includes: a module board that includes a first principal surface and a second principal surface on opposite sides of the module board; a power amplifier; a first circuit component; and a power amplifier (PA) control circuit configured to control the power amplifier. The power amplifier includes: an input terminal; an output terminal; first and second amplifying elements disposed parallel to the input terminal; and an output transformer connected between the output terminal and output terminals of the first and second amplifying elements. The PA control circuit is disposed on the second principal surface, and the first and second amplifying elements are both disposed on the first principal surface.
