  • Caracterización del ruido de fase de los subsistemas que integran un oscilador sintetizado 

    Barba, J.M.; Torres Torres, Francisco; Corbella Sanahuja, Ignasi (1992)
    Conference report
    Open Access
    A set of phase noise measurement techniques, based on the HP 3048A system, are compared in terms of major applications and limitations. To ilustrate the items, several significant measures are discussed.

    Canals Casals, Josep (Universitat Politècnica de Catalunya, 2013-06-27)
    Master thesis (pre-Bologna period)
    Open Access
    Covenantee:  Universität Stuttgart
    [ANGLÈS] Study, design and manufactoring of one Oscillator in resonant frequency of 6 GHz. One microwave cavity and two amplifiers are used as a principal parts of the circuit.
  • Desenvolupament i estudi comparatiu d'oscil·ladors locals per a un radiòmetre en banda L 

    Castro Ríos, Eva (Universitat Politècnica de Catalunya, 2016-09)
    Master thesis (pre-Bologna period)
    Open Access
    This thesis has been developed in the frame of the ESA scientific mission SMOS. Its purpose is to retrieve data about the soil moisture and ocean salinity in order to track extreme meteorological phenomena and to improve ...
  • Energy efficiency of non-synchronized pulsed actuations on leaky resonators 

    Domínguez Pumar, Manuel (2013-08-01)
    Article
    Restricted access - publisher's policy
    The purpose of this work is to analyze the optimality of pulsed actuations of leaky resonators when the ratio between the resonator and sampling frequencies is irrational. This is the case when the actuation system and ...
  • Instability mechanisms of fluidic oscillators 

    Suárez Martínez, Guillermo (Universitat Politècnica de Catalunya, 2017-09-15)
    Bachelor thesis
    Open Access
    In this work, direct numerical simulation of the Navier-Stokes equations governing incom- pressible fluid flow has been employed to analyze the various flow topologies observed in a two-dimensional fluidic oscillator at ...
  • Mezclador autooscilante con FET de AsGa en banda X. Consideraciones de diseño 

    Corbella Sanahuja, Ignasi; de los Reyes, Elías; Elias Fusté, Antoni (1998)
    Conference report
    Open Access
    Using a single active device as a non linear element both oscillating and mixing functions are acomplished. A method of design that uses a dielectric resonator as a frequency selective network is given.
  • PLL de microondas con tiempo de adquisición reducido 

    Berenguer Sau, Jordi; Artal, E.; Corbella Sanahuja, Ignasi; Comerón Tejero, Adolfo (1986)
    Conference report
    Open Access
    The behaviour of a PLL where the VCO is injection-locked to the reference frequency is studied. It is experimentally shown that the phase acquisition time can be reduced relative to the non-injection locked VCO situation. ...
  • Submillimeter receivers: local oscillators and mixers 

    Comerón Tejero, Adolfo (1978)
    Conference report
    Open Access
    With submillimetric (SUBMM) devices, lasers and mixers, the classical microwave techniques may be extended up to the SUBMM range. The best choice for the local oscillator seems to be the optically pumped FIR laser because ...
