Santa Barbara, Calif.-based Moseley recently introduced a line of COFDM microwave products for DTV STL applications. The DTV-Link product can be switched to either 45 Mbps or 155 Mbps rates in software and it uses various versions of QAM modulation.
Using an integrated multiplexer, the DTV-Link can deliver simultaneous DVB-ASI and NTSC video, with additional channels for T-1 or LAN connectivity. The standard DTV-Link radio uses a 1 W transmitter and an outboard linear amplifier is available to boost the power as high as 8 W.
