摘要

A method and system for adaptive operation of a power amplifier of an RFID reader device enables more efficient power management of the reader device. The method includes transmitting an RF interrogation signal from an antenna of the RFID reader device (step 505). A reflected signal is then received as a partial reflection of the interrogation signal (step 510). A return loss value is then estimated by comparing at least one parameter of the interrogation signal and at least one parameter of the reflected signal (step 515). Finally, an operating point of the power amplifier is adjusted in response to the return loss value (step 520).
