Abstract
A beam forming device, a calibration method and a calibration system using the same are provided. The beam forming device includes a processor, a memory unit, a baseband circuit, and a plurality of antenna modules. The baseband circuit is electrically connected to the processor and the memory unit. The plurality of antenna modules each include multiple antenna elements, multiple phase shifters and multiple amplifiers corresponding to the multiple antenna elements. The memory unit stores a plurality of reference codebooks and instruction data, the plurality of reference codebooks each have a reference angle and the reference angles are different from each other, and the instruction data is used to specify a predetermined codebook from the plurality of reference codebooks to control multiple antenna modules, thereby enabling multiple antenna modules to transmit and receive signals.
