Abstract
A stabilized all-photonic link is described that significantly simplifies X-band (approximately 8 to 12.5 GHz) and Ka-band (approximately 18 to 40 GHz) signal transport for high-performance antenna array applications. A cost-effective, integrated fiber-optic calibration technology provides long-term phase stability in the actual link used for broadband signal transport. This should directly benefit antenna array downlink applications that require signal phase alignment at a central site in order to correlate received signals. It also provides direct benefit to antenna array uplink applications that require phase alignment of all transmitted signals at the receiving target. We report the general design concepts with applicability to downlink/uplink array designs and present initial phase sensitivity tests and stabilization results.
