US Patent 12021312 Optically synchronized phased array

Disclosed herein is a phased antenna array which is configured to provide a signal through multiple antennas. The phased antenna array may include a plurality of sub-arrays. Each sub-array may include a complete and functional optically synchronized integrated circuit including an integrated photo diode. Advantageously, integrating the photo diode into the integrated circuit may reduce the size of the sub-array and decrease the length the high frequency timing signal is passed.
