Abstract:
1. An apparatus for stabilization of transmission power during an active transmission phase of a radio having an inactive transmission phase arranged between subsequent active transmission phases, comprising: a sensor adapted to measure a transmission power at predetermined measurement times associated with the active transmission phases; a system controller adapted to determine a power correction profile for the active transmission phases using the measured transmission power; a gain factor correction unit adapted to correct a gain factor of the apparatus during the active transmission phases in accordance with the determined power correction profile associated with a previous active transmission phase, the active transmission phases being separated by an inactive transmission phase associated with a reduced transmission power; and a power amplifier operable to amplify a transmission signal during the active transmission phases in accordance with the corrected gain factor, and to reduce the transmission power in the inactive transmission phase with respect to the transmission power during the active transmission phases.
