Patent ID: 7409196

Claim:
A radio frequency integrated circuit (RFIC) transmitter comprises: a digital transmitter processing module coupled to convert outbound data into an outbound baseband signal, wherein, when a gain adjust signal is provided to the digital transmitter processing module, gain of the outbound baseband signal is adjusted in accordance with the gain adjust signal; digital to analog converter coupled to convert the outbound baseband signal into an outbound analog baseband signal, wherein, when the gain adjust signal is provided to the digital to analog converter, gain of the outbound analog baseband signal is adjusted in accordance with the gain adjust signal; filter and gain module coupled to filter the outbound analog baseband signal to produce a filtered outbound analog baseband signal, wherein, when the gain adjust signal is provided to the filter and gain module, gain of the filtered outbound analog baseband signal is adjusted in accordance with the gain adjust signal; an up-conversion module coupled to convert the filtered outbound analog baseband signal into a radio frequency (RF) signal based on a local oscillation, wherein, when the gain adjust signal is provided to the up-conversion module, gain of the RF signal is adjusted in accordance with the gain adjust signal; a power amplifier coupled to amplify the RF signal to produce an outbound RF signal, wherein, when the gain adjust signal is provided to the power amplifier, gain of the outbound RF signal is adjusted in accordance with the gain adjust signal; and a transmit signal strength module coupled to generate the gain adjust signal based on a measure of transmit power of the outbound RF signal, wherein the transmit signal strength module provides the gain adjust signal to at least one of the digital transmitter processing module, the digital to analog converter, the filter and gain module, the up-conversion module, and the power amplifier.
