  • Method and arrangement for adjusting output power of a transmitter power supply
    Patent number: 6654592
    Abstract: The invention relates to a method and an arrangement implementing the method for adjusting output power of a transmitter power supply, in which method the output power of the power supply is measured and the output power of the power supply is adjusted on the basis of the measured output power. In the method, the output power of the transmitter power supply is adjusted on the basis of the transmission power of the transmitter such that a power supply control unit receives from the transmitter a synchronization chopping that synchronizes the operation between the transmitter and the power supply control unit, and the power supply control unit receives from the transmitter the information on the transmission power of the transmitter.
