Assignee: SILICON LABORATORIES INC.
Field: Telecommunications (Electrical engineering)
Classification: CPC H | IPC H

Claim 15:
16. A wireless device comprising:
a first integrated circuit comprising a radio frequency (RF) front end module, the RF front end module comprising:
a transmit path to receive, process and output a transmit RF signal, the transmit path comprising a power amplifier; and
a detector circuit to detect a level of the transmit RF signal; and

a second integrated circuit coupled to the first integrated circuit, the second integrated circuit comprising:
a host processor;
baseband circuitry coupled to the host processor to process an output signal, the baseband circuitry comprising a pre-driver to adjust a level of the output signal;
upconversion circuitry to upconvert the output signal to the transmit RF signal;
an RF circuit coupled to the upconversion circuitry, the RF circuit to process and output the transmit RF signal to the first integrated circuit;
a memory coupled to the host processor; and
a controller coupled to the host processor and the memory, the controller comprising an engine, wherein in response to a plurality of timer expirations during a preamble of the transmit RF signal, the engine is to obtain measurement information regarding a level of the transmit RF signal, store the measurement information into the memory, and inform the controller regarding the storage of the measurement information into the memory;
wherein the controller is to update a level of at least one of the pre-driver or the RF circuit one or more times during the preamble of the transmit RF signal, based at least in part on the measurement information.
