  • Architecture of a base station of a radio communications system
    Publication number: 20030153359
    Abstract: A base configuration of a micro-base transceiver station (MicroBTS) has a minimum volume and at least one add-on module that is connected to the base configuration. The modular construction according to a building-block principle enables the minimal base configuration of a micro-base station to be expanded in a versatile manner by adding add-on modules at any time to enlarge the base station by imparting additional technical features.

  • 1-bit digital-analog converter to convert digital information into current and voltage pulses
    Patent number: 6549152
    Abstract: A 1-bit digital-analog converter has outputs, switching units and pulse shaping units, with outputs, switching unit and the pulse shaping units being decoupled from one another by decoupling units. In addition, a 1-bit digital-analog converter has one or two outputs, two inputs, a switching unit and pulse shaping units, with each input being produced in a pair, and for each switching unit a second switching unit is arranged such that each bit change of the input bit fundamentally forces a switching operation. In addition, in the case of the current circuit i, the current i is regulated to virtually or actually zero, while in the case of the voltage circuit the corresponding voltage difference is regulated to virtually or actually zero.
