Abstract:
A transmitter circuit designed to operate over a specified transmit frequency range, comprising:(a) an oscillator configured to generate a first signal at a first frequency; (b) an up-converter configured to convert the first signal into a second signal at a second frequency different from the first frequency, wherein the second frequency falls within the specified transmit frequency range and is specified by frequency information available within the up-converter; and (c) an amplifier configured to amplify the second signal, wherein: the up-converter generates a control signal for the amplifier based on the frequency information used to specify the second frequency; the amplifier uses the control signal to automatically optimize its operations for amplifying the second signal; the specified transmit frequency range is a base station forward-link transmit frequency range for a wireless telecommunication system; the second frequency corresponds to a specific frequency block within the base station forward-link transmit frequency range; and the control signal identifies a sub-range within the base station forward-link transmit frequency range corresponding to the specific frequency block.
