摘要：Circuitry includes a first RF power amplifier, a second RF power amplifier, a thirdRF power amplifier, a first bias signal generator, and a second bias signal generator. Thefirst RF power amplifier and the second RF power amplifier are each configured toamplify 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 firstmode, the first bias signal generator provides a bias signal to the first RF power amplifierand the second bias signal generator provides a bias signal to the second RF poweramplifier. In a second mode, the first bias signal generator and the second bias signalgenerator each provide a portion of a bias signal to the third RF power amplifier.
