Classification: CPC H | IPC H

Claim 0:
1. An apparatus comprising:
a transmit path to receive, process and output a transmit radio frequency (RF) signal, the transmit path comprising a power amplifier to amplify and output the transmit RF signal; and
a detection circuit coupled to the transmit path, the detection circuit 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, wherein based at least in part on the level of the transmit RF signal at at least one of the input or the output of the power amplifier, a level of at least one component of the transmit path that is upstream to the power amplifier is to be updated, to control a transmit power variation of the transmit RF signal.
