Abstract
A transmission frontend includes a modulator configured to generate a modulated signal. A first selectable path is electrically coupled to the modulator and is configured to generate a first signal having a first power level. A second selectable path is electrically coupled to the modulator and is configured to generate a second signal having a second power level. The first power level is greater than the second power level. A transformer is electrically coupled to each of the first selectable path and the second selectable path. An antenna is electrically coupled to the transformer.
