Abstract
In one aspect, an apparatus comprises a transmit path including a power amplifier to receive, process and output a transmit radio frequency (RF) signal the transmit path comprising a power amplifier. A detection circuit coupled to the transmit path may be configured to: detect, during a first portion of a packet of the transmit RF signal, a level of the transmit RF signal at an input to the power amplifier; and detect, during a second portion of the packet of the transmit RF signal the level of the transmit RF signal at an output of the power amplifier. Based at least in part on the detected level at at least one of the power amplifier input or output, a level of at least one component of the transmit path upstream to the power amplifier is to be updated, to control a transmit power variation of the transmit RF signal.
