The granting of US patent 9,473,197 and European patent EP2951930 has been announced by SRT Marine Systems, for its Reversible Time Domain Duplex (RTDD) transceiver technology. Developed entirely in-house by SRT’s radio technology engineering team RTDD is integrated into SRT’s AIS transceivers to simultaneously reduce cost and size whilst also improving performance.
The technology enables a specific single RF architecture to be used simultaneously for both receiving and transmitting through electronic reversing of the RF chain between receive and transmit. This is achieved through a complex combination of intelligent selection of intermediate frequencies and fast switching.
Simon Tucker, CEO of SRT Marine Systems said: “Since 1999, SRT have been the global leaders in AIS core technology development. This patent demonstrates the innovation and capability of SRT’s R&D department who have again delivered technology that will deliver substantial benefits to our AIS transceiver customers.”
He added: “I would like to personally thank our team for their excellent work and look forward to announcing their next technology innovation.”
