Abstract:
Technologies directed to binning methods for electronically steered transmit phased arrays with amplitude tapering are described. One communication system includes a first and a second set of power amplifiers. The first set operates with a first peak power level and the second set operates with a second peak power level that is lower than the first peak power level. A digital beamforming (DBF) device sends a first set of signals to the first set of power amplifiers causing the first set of power amplifiers to operate in a first range. The DBF also sends a second set of signals to the second set of power amplifiers causing the second set of power amplifiers to operate in a second range.
