Abstract

A photonic in-phase/quadrature (I-Q) RF phase shifter utilizing the signals from two integrated optic Mach-Zehnder modulators has been tested. This system demonstrates the capability of 360-deg phase control, less than 1-deg RF errors at constant amplitude, and less than 0.5-degree errors over a 30 dB RF amplitude taper. Using this technique, a four-channel beam forming network was also developed and integrated with a printed patch, lightweight phased array antenna. High accuracy linear beam control was achieved. Null patterns of more than 30 dB were produced on boresight. The null was steered to greater than 30-deg from boresight with a linear accuracy of about 1 deg.
