  • Memory-based amplifier load adjust system
    Publication number: 20030199256
    Abstract: A power amplifier load adjust system includes a power amplifier and a variable impedance network coupled to the output of the power amplifier. The variable impedance network presents a plurality of impedances to the output of the power amplifier responsive to a load control signal. A control circuit generates a transmit power command and a channel frequency command. Memory stores a plurality of control values as a function of output power and frequency. A processing circuit coupled to the variable impedance network, the control circuit, and the memory retrieves the plurality of control values and uses them to generate the load control signal in response to the transmit power command and the channel frequency command.
