CIRCUITS, DEVICES AND METHODS RELATED TO ANTENNA TUNER

Abstract:

Circuits, devices and methods related to antenna tuner. In some embodiments, an antenna can be tuned by amplifying a signal for transmission by operating a transistor with a base current, and monitoring the base current. The method can further include adjusting an antenna tuner to thereby adjust an antenna load impedance presented to the amplified signal, with the adjustment being based on a variation of the monitored base current.
