Abstract

A Voice-Data-RF IC includes voice and data baseband processing modules, voice and data RF sections, and an interface module. The voice baseband processing module and the voice RF section convert an outbound voice signal into an outbound RF voice signal and convert an inbound RF voice signal into an inbound voice signal. The data baseband processing module and the data RF section convert outbound data into an outbound RF data signal and convert an inbound RF data signal into inbound data, wherein the inbound RF data signals have a carrier frequency from a different inbound frequency band than the inbound RF voice signals and the outbound data RF signals have a carrier frequency from a different outbound frequency band than the outbound RF voice signals. The interface module conveys the inbound voice symbol stream and the outbound voice symbol stream between the voice baseband processing module and the voice RF section when the Voice-Data-RF IC is in a voice mode and conveys the inbound data symbol stream and the outbound data symbol stream between the data baseband processing module and the data RF section when the Voice-Data-RF IC is in a data mode.
