Patent ID: 8085869

Claim:
An integrated circuit radio transceiver operable to support wireless communications, comprising: a digital processor operable to produce outgoing digital data; conversion circuitry operable to produce continuous waveform signals based upon the outgoing digital data; radio front end transmit path circuitry including a mixer, at least one filter, a signal amplifier and a power amplifier all coupled in series in a transmit path and operable to collectively front end process the continuous waveform signals to produce outgoing radio frequency signals; at least one gain control module to selectively apply digital gain settings and power settings of the power amplifier of the transmit path circuitry to a desired total gain setting; second logic module to prompt the digital processor to produce a power amplifier pre-distortion digital signal superimposed on the outgoing digital data to counteract at least one of phase and amplitude distortion introduced by the radio front end transmit path circuitry wherein the characteristics of the pre-distortion digital signal correspond to the digital gain settings and power amplifier settings; a transmit-receive switch operably disposed to couple at least one antenna to at least one transmit path output or to at least one receive path and further disposed to couple a specified load to the at least one transmit path output whenever the antenna is coupled to the at least one receive path; and a feedback path operably coupling an output of the power amplifier to the digital processor.
