Abstract
An integrated circuit device is provided. In some examples, the integrated circuit device includes a first amplifier path, a second amplifier path coupled in parallel with the first amplifier path, a matching network coupled to the first amplifier path and the second amplifier path, and an antenna coupled to the matching network. In some such examples, the first amplifier path includes a first differential power amplifier coupled to the matching network, and the second amplifier path includes a second differential power amplifier coupled to the matching network. The integrated circuit device may further include a controller coupled to selectively enable the first amplifier path to provide a transmitter output power within a first range and to selectively enable the second amplifier path to provide a transmitter output power within a second range that is different from the first range.
