Visit us at www.work-microwave.deDual Channel, Shared OscillatorDownconverterS-, Ku-, Ka-BandTriple Channel Converters also availableAlso available as Outdoor VersionThe satellite downconverters developed andmanufactured by WORK Microwave are designed tomeet the requirements of modern satellitetransmission. Customers worldwide appreciate theirreliability and high level of quality. These types of dualchannel, shared oscillator converters can be used insystems, where an accurate phase relationship isrequired between two converter channels, as it is e.g.the case for monopulse tracking system downconversion.Operating and controlThe converters can be operated via the push buttonson the front panel using self-explanatory displaymenus or via remote control (RS232, RS422/485,TCP/IP over Ethernet).Detailed monitoring of the system status and a summaryalarm output (dual change over switch contacts)are provided. For the remote control either ASCIIstring based commands as well as addressable,packet based commands are provided.Housing optionsThe converters normally are delivered without fansand can be operated in environments, where atminimum 1 RU space for natural ventilation isavailable above each unit. This eliminates the fan aspotential point of failure. For rack installations withoutany space in between the units a fan within theconverter unit is recommended, which forces anairflow from the right side to left side of the units.Outdoor versions with IP67 degree of protection arealso available.Key featuresShared oscillator to guarantee excellent phasetracking in between channels70 MHz or 140 MHz IF bands availableLow power consumptionExtreme low phase noise (< -60 dBc/Hz @ 10 Hz)Long- term stability 10 -7 / yearOutput power +10 dBm (1 dB compression point)Automatic reference recognition (5 and 10 MHz)0°C to 50°C (32°F to 122°F) (SCD units)-30°C to 60°C (-22°F to 140°F) (HCD units)Remote control through RS232, RS422/485(2-wire or 4-wire) interfaces.
