ABSTRACT:
A linear high powered integrated circuit transmitter includes an up-conversion module, a plurality of power amplifiers, balanced integrated circuit coupling, and a combining circuit. The up-conversion module is operably coupled to produce a differential up-converted signal by mixing one or more local oscillations with a low intermediate frequency (IF) signal. The balanced integrated circuit coupling couples the plurality of power amplifiers to the up-conversion module such that the power amplifiers amplify the up-converted signal to produce a plurality of amplified radio frequency (RF) signals. The combining circuit is operably coupled to combine the plurality of amplified RF signals to produce a transmit RF signal.
