1. An apparatus configurable to operate in either a separate power amplifier configuration or a combined power amplifier configuration, the apparatus comprising:
- a transformer including;
a first transformer winding coupled to first and second differential inputs; and
a second transformer winding coupled to a first single-ended output and a second single-ended output;
a first switch coupled to the first single-ended output of the transformer;
a second switch coupled to the second single-ended output of the transformer;
wherein the transformer, while configured to operate in the separate power amplifier configuration, is configured to either output a signal associated with a first operating mode onto the first single-ended output of the transformer or output a signal associated with a second operating mode onto the second single-ended output of the transformer; and
wherein the transformer, while configured to operate in the combined power amplifier configuration, is configured to output signals associated with the first operating mode and/or the second operating mode onto the first single-ended output of the transformer, and with the second single-ended output being unused.

13. A method comprising:
configuring a transformer of a wireless transmitter to operate in either a separate power amplifier configuration or a combined power amplifier configuration, wherein the configuring the transformer to operate in a separate power amplifier configuration includes configuring the transformer to either output a signal associated with a first operating mode onto the first output of the transformer or to output a signal associated with a second operating mode onto a second output of the transformer, wherein the configuring the transformer to operate in a combined power amplifier mode includes configuring the transformer to output signals associated with the first operating mode and/or the second operating mode onto the first output of the transformer, and with the second output of the transformer being unused. - View Dependent Claims (14, 15)
