A radio frequency (RF) transmitter includes a baseband processing module, an up conversion module, a power amplifier module, and an antenna assembly. The baseband processing module is coupled to convert outbound data into a first outbound symbol stream and a second outbound symbol stream and to generate an adjust signal. The up conversion module is coupled to convert the first outbound symbol stream into a first up converted signal and to convert the second outbound symbol stream into a second up converted signal. The power amplifier module is coupled to amplify the first and second up converted signals to produce first and second outbound RF signals. The antenna assembly is coupled to transmit the first and second outbound RF signals, wherein the antenna assembly adjusts at least one of amplitude and phase of at least one of the first and second outbound RF signals based on the adjust signal.
