Abstract
An apparatus ( ), and method, for calibrating gain in satellite uplink receiver electronics includes an uplink receiver, a measurement processor, and an attenuator ( ). The measurement processor receives the uplink signal from the uplink receiver and includes circuitry to sample ( ) the uplink signals during a blanking interval and outputs a gain calibration signal. The sampling circuitry ( ) may sample uplink signals periodically or responsive to extreme changes in conditions, and may sample the uplink signal multiple times during a blanking interval to output a multiple measurement sample. The measurement processor may include averaging circuitry ( ) to produce a sample average. The method and apparatus ( ) may both be used with TDMA systems.
