    • A method and device for optimizing an operating point of a power amplifier (40) in a WCDMA mobile terminal (10) is provided. The method includes the steps of receiving a first signal; determining a TFCI value from the first signal; determining a status of a compressed mode of the mobile terminal (10); determining a required power output level of the mobile terminal (10); reading an operating point value from a memory in response to the three determined values; and supplying the operating point value to the power amplifier (40). The operating point value is indicative of a bias current. The device includes a processor (41) for determining a TFCI value, a compressed mode status, and a required power output level from a control signal; a state machine (42) for retrieving from a memory an operating point value of a power amplifier (40) in response to the three values; and the power amplifier (40) for amplifying a transmission signal.
