ABSTRACT:
A novel out-phasing-array transmitter system and method are disclosed. The method is based on decomposing the input signal into an array of signals to drive a general, multiple paths out-phasing-array transmitter. This decomposition is less sensitive to the phase difference between the multiple paths, and extends the dynamic range of the out-phasing-array transmitter system. The wide dynamic range and the multiple transmission paths increase the maximum achievable output power, in accordance with the WiMAX specifications.
