Abstract :
This paper proposes a new architecture for mobile phone front-ends that dramatically reduces the complexity of multi-band smart phones. Traditional smart phone front-ends consist of many parallel transmit (Tx) and receive (Rx) chains each dedicated to a single band. The proposed architecture simplifies this by making few fully frequency tunable Tx and Rx chains that each cover multiple bands.
