Delay control in time diversity transmitter

摘要

Detectors 106a, 106b detect RF output signals of transmission units 100a, 100b, and output detection signals. A comparator 107 compares the detection signals output from the detectors 106a, 106b and outputs a comparison signal. On the basis of the comparison signal output from the comparator 107, a delay amount control circuit 108 controls delay circuits 102a, 102b so that the modulation timing is coincident at the transmission output terminal.
