Abstract

See full text

Circuitry includes a first RF power amplifier, a second RF power amplifier, a third RF power amplifier, a first bias signal generator, and a second bias signal generator. The first RF power amplifier and the second RF power amplifier are each configured to amplify RF signals for transmission in a first carrier network. The third RF power amplifier is configured to amplify RF signals for transmission in a second carrier network. In a first mode, the first bias signal generator provides a bias signal to the first RF power amplifier and the second bias signal generator provides a bias signal to the second RF power amplifier. In a second mode, the first bias signal generator and the second bias signal generator each provide a portion of a bias signal to the third RF power amplifier.
