US Patent 7409196 RFIC transmit power control

An RFIC transmitter includes a digital transmit processing module, a digital to analog converter, a filter and gain module, an up-conversion module, a power amplifier, and a transmit signal strength module. The transmit signal strength module is coupled to generate a gain adjust signal based on a measure of transmit power of an 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.
