Abstract :
Experiments performed on a 2×4 active MMIC based phased array antenna system are described. The active MMICs operating at C-band are controlled and fed via fiber optic links. The T/R level data mixing scheme for up-conversion (down-conversion) of the IF (RF) to RF (IF) is demonstrated. The phased array at C-band is characterized in an anechoic chamber. Optical true-time delay measurements to overcome beam squint are proposed.
