Patent ID: 8787851

Claim:
A system for power amplifier control, the system comprising: an automatic gain controller; a variable gain amplifier having an input coupled to an output of the automatic gain controller; a fixed gain amplifier having an input coupled to an output of the variable gain amplifier and having an output coupled to an input of the automatic gain controller; a radio frequency antenna having an input coupled to the output of the fixed gain amplifier; a storage module; and a processor, configured to: before the fixed gain amplifier is disabled and after the automatic gain controller adjusts gain for a last time, read a reference transmit power value from the automatic gain controller, read a gain level from the fixed gain amplifier, and save the reference transmit power value and the gain level in the storage module; and before the fixed gain amplifier is enabled and after the automatic gain controller adjusts gain for the last time, write the reference transmit power value saved in the storage module into the automatic gain controller and write the gain level saved in the storage module into the fixed gain amplifier.
