  • Comparative ownership costs of UHF TV transmitters 5-15 kW peak sync

    Publication Year: 1988, Page(s):8/1 - 821
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (364 KB)

    For some years now there has been considerable interest in comparing the true ownership costs of tetrode and klystron UHF TV transmitters. This interest recently intensified with the advent of the all-solid-state transmitters up to the 40 kW peak sync level (PS). The author has attempted to arrive at the comparative ownership costs of the three types of transmitter and to show which is the most ec... View full abstract»

  • New developments in transistorised TV transmitters

    Publication Year: 1988, Page(s):7/1 - 7/7
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (212 KB)

    Deals with new developments in solid state TV transmitters and describes some of the author's current work in this field. The range of high power solid state VHF and UHF TV transmitters developed by THOMSON-LGT uses a common set of techniques, including amplifiers power combining systems, DC power supply and distribution systems. The common set of techniques are illustrated by reference to the 30 ... View full abstract»

    The Independent Broadcasting Authority (IBA) builds, owns and operates the transmitting equipment used to carry the programmes of the Independent Television and the Independent Local Radio Companies. The television programmes are brought to over 99% of the population by two UHF transmitter networks. The IBA has a vast experience in the procurement, operation and maintenance of UHF solid state tran... View full abstract»

  • A newly designed UHF solid-state television transmitter

    Publication Year: 1988, Page(s):2/1 - 217
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (520 KB)

    This brand new television transmitter (TV TX) is a fully transistorized TV transmitter using a 6 kW UHF transistor power amplifier (V6KDU TR PA) composed of eight 800 W transistor power amplifier modules and allows all solid-state UHF TV transmitters with high output powers to be achieved. This TV transmitter achieves a high reliability and maintainability by using a complete plug-in type connecti... View full abstract»

  • Design philosophy for solid state transmitters

    Publication Year: 1988, Page(s):3/1 - 3/5
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (256 KB)

    Many aspects of the complete transmitter design such as the number and size of RF modules, the number of power supplies, the cooling arrangement, method of combining modules, drive arrangement and, in the case of television, the method of combining sound and vision signals, all require consideration. A transmitter which meets all these requirements can be used without the need for a complete reser... View full abstract»

  • A modular approach to solid state AM broadcast transmitters

    Publication Year: 1988, Page(s):4/1 - 4/4
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (236 KB)

    The gradual movement from transmitters employing thermionic valves to transmitters using transistors has almost always been accompanied by the use of a `modular' form of construction. For powers exceeding 100 Watts or so a multiplicity of devices is required. There are technical problems in merely connecting the devices in parallel or series, so the resultant circuitry obviously divides into a num... View full abstract»

  • Technologies for all solid state TV transmitter

    Publication Year: 1988, Page(s):5/1 - 5/4
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (192 KB)

    Toshiba developed an all solid state 50 kW VHF TV transmitter and an all solid state 30 kW UHF TV transmitter in 1985. The technologies embodied in these solid state transmitters are described. The 50 kW visual power amplifier block consists of forty 1.5 kW visual power amplifiers, and the 12.5 kW aural power amplifier block is composed of ten 1.5 kW aural power amplifiers. These power amplifiers ... View full abstract»
