Reconfigurable transmit digital-to-analog converter (DAC) circuit

A digital-to-analog converter (DAC) circuit comprising:

• a first DAC;
• a first set of one or more switches coupled between an output of the first DAC and a first output of the DAC circuit;
• a second DAC;
• a second set of one or more switches coupled between an output of the second DAC and a second output of the DAC circuit;
• a third DAC;
• a third set of one or more switches coupled between an output of the third DAC and a third output of the DAC circuit;
• a fourth DAC;
• a fourth set of one or more switches coupled between an output of the fourth DAC and a fourth output of the DAC circuit;
• a fifth set of one or more switches coupled between the output of the first DAC and a fifth output of the DAC circuit;
• a sixth set of one or more switches coupled between the output of the second DAC and the fifth output of the DAC circuit;
• a seventh set of one or more switches coupled between the output of the third DAC and a sixth output of the DAC circuit;
• and
• an eighth set of one or more switches coupled between the output of the fourth DAC and the sixth output of the DAC circuit, wherein the DAC circuit is configured to:
• use the first, second, third, and fourth outputs with a first set of one or more frequency bands;
• and
• use the fifth and sixth outputs with a second set of one or more frequency bands, different from the first set of one or more frequency bands.
