A cellular phone IC(Integrated Circuit) and an application thereof are provided to implement baseband and RF circuits on a single IC die so as to support a plurality of wireless communication standards. A voice data RF IC comprises a baseband processing module(174), an RF section(82), and an interface module(84). The baseband processing module converts an outbound voice signal into an outbound voice symbol stream, and converts an inbound voice symbol stream into an inbound voice signal. Also the baseband processing module converts outbound data into an outbound data symbol stream, and converts an inbound data symbol stream into inbound data. The RF section converts an inbound RF voice signal and an outbound voice symbol stream into an inbound voice symbol stream and an outbound RF voice signal respectively. Also the RF section converts an inbound RF data signal into an inbound data symbol stream, and converts an outbound data symbol stream into an outbound RF data signal. The interface module provides connections between the baseband processing module, the RF section, and chip external circuits.
