    摘要: A method for regulating a power amplifier for operation in a timeslot data transmission system comprises providing the power amplifier with a bias for setting an operating point for the power amplifier, wherein the bias has a respective bias value. In addition, a supply voltage control signal is provided, wherein a supply voltage value is set such that a prescribed output power value of the power amplifier is attained. The bias value is changed to a new bias value. These steps are repeated until a prescribed criterion is met, but for at least one subsequent timeslot. Next the bias value of the subsequent timeslot is set to the bias value of the previous timeslot.
