  • Strategy for using the envelope information within a closed loop power control system
    Patent number: 7970364
    Abstract: A power control system includes a reference path filter used to suppress high frequencies in an input signal and generate a filtered envelope signal, a reference path amplifier to scale the filtered input signal based on a gain signal and generate a reference signal, a signal path amplifier to amplify an RF modulated signal and generate a signal path output signal scaled by a gain of an actuator signal, and a power detector to detect a power associated with the signal path output signal. The system includes an ADC to receive, pre-filter and convert the detected envelope signal into a measurement signal, and a comparator block to receive the reference signal and the measurement signal, and generate an error signal based on the difference, and a controller to generate the actuator signal for controlling the gain of the signal path amplifier based on the error signal.

  • POWER CONTROL LOOP, TRANSMITTER WITH THE POWER CONTROL LOOP AND METHOD FOR CONTROLLING OUTPUT POWER OF A TRANSMITTER DEVICE
    Publication number: 20090156143
    Abstract: A power control loop includes a low-frequency signal path and a high-frequency signal path with the delay compensation block. The delay compensation block is used to determine a correlation between an average reference level and an average measured power level. The result may control a delay line to compensate a time misalignment in the power control loop.
