    Abstract: A system and method for combining the downlink signals from at least two transceivers to increase the power of the downlink signal. In-phase down link signals from at least two transceivers are combined to produce a downlink output signal having an output power level greater than the power level of any single downlink signal. Detector means, which samples the downlink signals to identify a phase difference is coupled to control a phase controller which adjusts the phase of at least one of the downlink signals to be in step with the phase of the other downlink signal. The phase controller maintains the downlink signals in phase by shifting the phase of at least one of the downlink signals relative to the other.
