  • Feed-forward technique to measure S-parameters under jamming CW high power out-of-band signals 

    González Rodríguez, Marta (Universitat Politècnica de Catalunya, 2017-07-07)
    Master thesis
    Open Access
    In recent years, high-power radio frequency (RF) devices have become increasingly common due in part, to the high-speed telecommunications industry. The evolution of mobile devices drives to the use of wireless applications ...
  • Feed-forward technique to measure the reflection coefficient under CW high-power signals 

    Collado Gómez, Juan Carlos; González Rodríguez, Marta; González Arbesú, José María; Mateu Mateu, Jordi; Verdú Tirado, Jordi; Hueltes Escobar, Alberto (IEEE Microwave Theory and Techniques Society, 2018-10-01)
    Article
    Open Access
    This paper describes a measurement setup to obtain the reflection coefficient response over the frequency of a given device when this is subjected to a single-tone high-power (HP) signal. The proposed system is based on a ...
  • Hybrid testbed of a free-space laser communications system for atmospheric turbulence compensation 

    González Rodríguez, Marta (Universitat Politècnica de Catalunya, 2016-07-27)
    Bachelor thesis
    Restricted access - author's decision
    In the last few years free-space laser communications have become a feasible and high-bandwidth wireless alternative to fiber optic cabling and radio frequency (RF) systems due to its extremely robustness against interference ...
  • New technique to cancel IMD3 in electroacoustic filters 

    González Rodríguez, Marta; Collado Gómez, Juan Carlos; González Arbesú, José María; Mateu Mateu, Jordi (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Conference lecture
