Space diversity in-phase synthesis circuit

摘要

PURPOSE:To simplify the whole circuit configuration by constituting the means for correcting the phase of a signal received by each antenna in the same way. CONSTITUTION:Each antenna 1-N receives the same radio wave, and outputs it as signals S1-SN to phase correcting means 301-30N. The means 301-30N all consist of the same constitution, all the same reference signals Sd generated from a reference signal generating means 33 are inputted thereto, and a correction for aligning the phase of each signal S1-SN with the phase of this inputted reference signal Sd is executed. The corrected signal outputted from each means 301-30N is synthesized by a signal synthesizing means 34 and outputted. In such a way, the whole circuit can be realized by simple constitution.
