    • Diseño de filtros de microondas mediante la teoría del acoplamiento modal 

      Bara, Javier; Comerón Tejero, Adolfo (Universidad de Sevilla, 1984)
      Text en actes de congrés
      Accés obert
      The behaviour of several non-independent resonant circuits is approached from coupled mode theory, the formulation of the energy (Hamiltonian) for the system and the Bethe theory for coupling through apertures. The design ...

    • El "Olympus Propagation Experiment (OPEX)". Aspectos del cabezal de R.F. de las estaciones receptoras 

      Comerón Tejero, Adolfo; Bara, Javier; Elias Fusté, Antoni; Corbella Sanahuja, Ignasi; Artal, Eduardo (1985)
      Text en actes de congrés
      Accés obert
      The design guidelines for a coherent receiver for the Olympus propagation experiment at 12.5, 20 and 30 GHz are discussed. The receiver channels can be locked to a main PLL in the 12.5 GHz channel, thus decreasing the loss ...

    • Improvement of the pull in range and acquisition time of a microwave PLL system by injection locking the V.C.O 

      Berenguer Sau, Jordi; Bara, Javier; Artal, Eduardo; Corbella Sanahuja, Ignasi (1987)
      Text en actes de congrés
      Accés obert
      The requirements of large pull-in range and short acquisition time in microwave and millimeter wave phase locked oscillators are of great importance since the free running VCO frequency may be sorne tens of MHz off the ...

    • Técnica de ajuste de la tensión offset en detectores de fase de microondas 

      Berenguer Sau, Jordi; Bara, Javier; Elias Fusté, Antoni (Universidad Politécnica de Madrid (UPM), 1988)
      Text en actes de congrés
      Accés obert
      In microwave phase-detectors for PLL applications, among the useful output signal a DC level appears, which has to be cancelled for a proper operation of the PLL's loop filter. In this paper we present a method for cancelling ...
