Harris has developed the Cool Play 1670, a television transmitter platform designed for 1670-MHz Digital Video Broadcasting Handheld (DVB-H) applications, including the Modeo mobile TV service planned for the U.S. Featuring convection-cooled technology, the platform can operate in harsh environments, including external temperatures from -40° to +45°C. As a result, it's equipped for outdoor installation without specialized cooling equipment. The platform's pcb coatings and air-handling systems ensure that the electronics within the Cool Play 1670 transmitters receive sufficient ventilation and cooling without corrosive effects from humidity or impurities in the air.
All the elements required for a local DVB-H transmitter, including satellite receiver, TV exciter, amplification, wireless or wired Ethernet modems, and uninterruptible power supplies are contained within the climate-controlled Cool Play 1670 cabinet. The transmitter is designed for easy deployment on rooftops and other difficult environments, and offers various redundancy options to ensure that the mobile TV service operates continuously. Power outputs range from 50 to 400 W, in single output and diversity transmitter configurations. More information is available at www.harris.com.
