    • Tunable dual-band filters based on capacitive-loaded stepped-impedance resonators 

      Girbau Sala, David; Lázaro Guillén, Antoni; Pérez, A.; Martínez, Ester; Pradell i Cara, Lluís; Villarino Villarino, Ramón (2009)
      Text en actes de congrés
      Accés obert
      This paper proposes the design of tunable dual-band filters for multi-band multi-standard systems. The main objective is to provide frequency tunability in the second band while maintaining the first band fixed. To this ...
