ABSTRACT:
A transmitter system includes a transmitter with a power amplifier. An antenna communicates with the power amplifier. A protection circuit generates a sensed signal that varies with an impedance of the antenna and reduces an output of the power amplifier in response to the sensed signal exceeding a predetermined threshold.
