Abstract:
A multi-standard transmitter architecture with digitally upconverted intermediate frequency (IF) outphased signals is disclosed. The transmitter architecture includes a Gallium Nitride (GaN) power amplifier (PA) circuit having a Current Mode Class-D (CMCD) configuration. The GaN PA circuit includes a lower switching device electrically coupled to an input to receive an input RF signal and an upper switching device to switchably electrically couple the first switching device to a power supply to drive an antenna circuit based on the input RF signal. Thus, a reconfigurable transmitter architecture is disclosed that utilizes a high-speed Gallium Nitride (GaN) driver to achieve a peak drain efficiency of at least 85% while delivering output power of 10 W at 1 GHz frequency, for example.

Claim (Index 10):
The transmitter system of  claim 1 , further comprising a digital upconvert stage, the digital upconvert stage comprising:\n an intermediate frequency (IF) processor for receiving a first signal (I(t)) representing an in-phase component of an output waveform and a second signal (Q(t)) representing the quadrature component of the output waveform, and outputting a first and second set of outphased IF signals; and digital upconvert circuitry to receive the first and second set of outphased IF signals and digitally upconvert the first and second set of outphased IF signals to provide the RF signal for driving the GaN PA circuit.
