摘要
A digitally controlled delay is applied to a microwave signal by applying the signal to a transmitter to modulate an optical wave which is transmitted by polarization holding optical fibers after its polarization is switched in TE or TM mode in switching units. An optical receiver reconstitutes a delayed microwave signal. Variation of the delay is controlled by delay select signals controlling the switching units. The principle finds particular application in phased array antenna systems.
