The rapidly changing RF landscape creates a requirement for flexible frequency access as well as the ability to move signals over long distances. This paper presents the characterization and experiments of a wide band photonics enabled transceiver. The architecture, SFDR, noise figure, and gain are presented, followed by the results of communications experiments involving up to 25 km of remoting fiber...
Broadband wireless transmission with tunable 5–40GHz carrier is demonstrated using photonic frequency conversion. The agile tuner allows ∼4 GHz of instantaneous bandwidth for both up- and down-conversion paths, without banding or channelization.
Demonstration of low conversion loss through the novel integration and packaging of high power photodiodes and a fragmented aperture antenna for a fiber-fed RF array.
Photonic components and technologies enable complimentary capability to enhance traditional RF and digital EW jammer system architectures. A trade study between RF and photonic architectures is performed to address switch matrix design for EW applications.
Photonic components and technologies augment and enhance traditional RF and digital EW jammer system architectures. Four identified capabilities enabled by photonics are simultaneous transmit and receive, frequency conversion, true-time delay, and photodiode/antenna integration.
