Abstract:
1. An integrated circuit (IC) for balancing I and Q components of digital modulated signals, the integrated circuit comprising: circuitry configured to amplify a Q component of the signals in accordance with a correction factor; circuitry configured to amplify an I component of the signals in accordance with the correction factor; circuitry configured to add the I component of the signals and an output of circuitry configured to amplify the I component for generating a phase balanced I component of the signals; circuitry configured to add the Q component and an output of the circuitry configured to amplify the Q component for generating a phase balanced Q component of the signals; circuitry configured to correlate the outputs of the circuitry configured to add the Q component and circuitry configure to add the I component; and circuitry configure to generate the correction factor from the correlation results.
