WSIU IOT60k Digital & 30 Kw Analog 2002

  1. 1. Southern Illinois University-Carbondale IL, Tamaroa, USA Catalin Popescu – 2001-2002
  2. 2. Project Goals <ul><li>60Kw-DIGITAL UHF transmitter – CH40, IOT parallel configuration system with a redundant cooling system; </li></ul><ul><li>RF system to allows any combination between the pair of the 30KW IOT’s and antenna system available, with no interruptions; </li></ul><ul><li>30Kw-ANALOG VHF transmitter –CH8, Traplexer, in a main / stand-by configuration;- the transmitter is shipped and tested with a conversion kit for future DIGITAL conversion; </li></ul><ul><li>Line optimized (VSWR better than 1.1), good insulation between the combined paths (more than 60dB) </li></ul><ul><li>Remote Control operation, realized thru a Moseley MRC-2 package; </li></ul><ul><li>Design the system for installation into a room with ceiling restrictions, existing equipment, air ducting, and HVAC Units; </li></ul>
  3. 3. Description <ul><li>RF system design according with the customer specifications. </li></ul><ul><li>Submission and approval of the proposal. </li></ul><ul><li>Manufacturing and Installation drawings. </li></ul><ul><li>Remote Control design for the application. </li></ul><ul><li>Helping the Test and Service Dept. in the final commissioning </li></ul>FOR MORE INFO... Mr. Catalin Popescu – Application Specialist Phone: 905 564-9222 Fax: 905 564-9224
  4. 4. RF system design <ul><li>IOT 60KW _UHF –CH40 System parallel configuration is designed to use (see IOT Data Sheet): </li></ul><ul><ul><ul><li>two IOTD2130 tubes (EEV); </li></ul></ul></ul><ul><ul><ul><li>WG Switchless Combiner (“Magic TEE”); </li></ul></ul></ul><ul><ul><ul><li>WG connections and Patching, combined with 6-1/8”, coaxial line; </li></ul></ul></ul><ul><ul><ul><li>Independent water cooling systems for each IOT and Loads; </li></ul></ul></ul><ul><li>The 30KW_VHF –CH8 Main/Stand-by configuration with an existing tube transmitter is designed to use: </li></ul><ul><ul><ul><li>1-5/8” for aural; </li></ul></ul></ul><ul><ul><ul><li>3-1/8” for visual and combined (aural +visual); </li></ul></ul></ul><ul><ul><ul><li>2 Exciters configuration, with a Traplexer (incl. 3.58 Traps and aural cavities); </li></ul></ul></ul><ul><ul><ul><li>Motorized 3-1/8” Coaxial switch for M/S config.. </li></ul></ul></ul><ul><li>The key factors for design where: max line avg. power, VSWR derating, insertion loss contribution to final power at the gas barrier and space limitations. </li></ul>
