Abstract: A programmable transmitter circuit may be coupled to a controller circuit. The controller circuit may be configured to generate control signals based at least on a signal. The transmitter circuit may include a plurality of unit cells. Each unit cell may include a respective first current source and a respective second current source. Each unit cell may be configured to be set in an activated state or a deactivated state based at least on the control signals. For a unit cell of the plurality of unit cells, when the unit cell is set in the activated state, the respective first current source or the respective second current source may be configured to generate a current to be applied to a load.

Abstract: A transmitter architecture and methodologies supporting uplink inter-band carrier aggregation (CA). In various embodiments, first and second baseband signals are provided to a plurality of passive mixers that selectively combine the baseband signals with differing local oscillation signals to produce outbound RF signals of at least first and second RF frequencies. Depending on the relevant CA mode of operation, the outbound RF signals are amplified and selectively coupled to at least one transmitting antenna for respective transmission over a plurality of frequency bands.

Abstract: A wireless communications transmitter is divided into N binary weighted communication signal processing paths including both fixed and variable gain communication signal processing chains. Specific bit sequences are used to select a combination of fixed and variable gain signal processing paths to adjust to a desired transmitter output power. Alternately, high and low power communication signal processing paths are chosen as needed with the high power communication signal processing path including an odd order harmonic notch filter.
