Abstract: The present invention generally relates to the field of automatic power control (APC) circuitries used in the analog front end of a mobile transmitter. It particularly refers to a power control circuitry and a corresponding method for controlling the power level of an RF signal to be transmitted at the output port of a variable-gain power amplifier by performing an additional regulation of the APC loop's reference signal. Thereby, it is proposed to increase the radiated RF power in case a transmitting antenna is mismatched to said power amplifier in order to not release an ongoing call. In case there is a subject very close to the terminal antenna, the antenna load is changed and the increased reflected signal is measured.

Abstract: The present invention generally relates to the field of automatic power control (APC) circuitries used in the analog front end of a mobile transmitter. It particularly refers to a power control circuitry (101M, 101N) and a corresponding method for controlling the power level (Pout) of an RF signal (x(t)) to be transmitted at the output port of a variable-gain power amplifier (105) by performing an additional regulation of the APC loop's reference signal (Vref). Thereby, it is proposed to increase the radiated RF power (Pout) in case a transmitting antenna (110) is mismatched to said power amplifier (105) in order to not release an ongoing call. In case there is a subject very close to the terminal antenna, the antenna load is changed and the increased reflected signal is measured.
