    • Design procedure for new compact waffle-iron ilters with transmission zeros 

      Teberio Berdún, Fernando Upna; Percaz Ciriza, Jon Mikel Upna; Arregui Padilla, Iván Upna; Martín Iglesias, Petronilo; Lopetegui Beregaña, José María Upna; Gómez Laso, Miguel Ángel Upna; Arnedo Gil, Israel Upna (IEEE, 2018)   Artículo / Artikulua  OpenAccess
      In this paper, a novel waffle-iron filter with transmission zeros at multiple frequencies, along with its design procedure, is presented. The proposed filter features a high-power behavior and a wide rejected band in a ...
    • General synthesis of tapered matching sections for single mode operation using the coupled-mode theory 

      Percaz Ciriza, Jon Mikel Upna; Arnedo Gil, Israel Upna; Arregui Padilla, Iván Upna; Teberio Berdún, Fernando Upna; Martín Iglesias, Petronilo; Gómez Laso, Miguel Ángel Upna; Lopetegui Beregaña, José María Upna (IEEE, 2019)   Artículo / Artikulua  OpenAccess
      In this paper, a novel and general method to synthetize microwave waveguide tapers intended for single mode operation is proposed. The technique is based on the use of an exact series solution of the inverse scattering ...
    • High-power filter design in waveguide technology: future generation of waveguide satellite filters in payloads handling increasing bit rates and numbers of channels 

      Arregui Padilla, Iván Upna; Teberio Berdún, Fernando Upna; Arnedo Gil, Israel Upna; Percaz Ciriza, Jon Mikel Upna; Martín Iglesias, Petronilo; Lopetegui Beregaña, José María Upna; Gómez Laso, Miguel Ángel Upna (IEEE, 2020)   Artículo / Artikulua
      To design a filter for a particular application, many issues must first be considered. Which technology will be the most convenient? What design technique will provide better results for a particular set of frequency ...
    • Rectangular waveguide filters with meandered topology 

      Teberio Berdún, Fernando Upna; Percaz Ciriza, Jon Mikel Upna; Arregui Padilla, Iván Upna; Martín Iglesias, Petronilo; Lopetegui Beregaña, José María Upna; Gómez Laso, Miguel Ángel Upna; Arnedo Gil, Israel Upna (IEEE, 2018)   Artículo / Artikulua  OpenAccess
      In this paper, a new topology for rectangular waveguide bandpass and low-pass filters is presented. A simple, accurate, and robust design technique for these novel meandered waveguide filters is provided. The proposed ...
    • Routing with classical corrugated waveguide low-pass filters with embedded bends 

      Teberio Berdún, Fernando Upna; Percaz Ciriza, Jon Mikel Upna; Arregui Padilla, Iván Upna; Martín Iglesias, Petronilo; Lopetegui Beregaña, José María Upna; Gómez Laso, Miguel Ángel Upna; Arnedo Gil, Israel Upna (EMW Publishing, 2018)   Artículo / Artikulua  OpenAccess
      A very simple design method to embed routing capabilities in classical corrugated filters is presented in this paper. The method is based on the calculation of the heights and lengths of the so-called filters design ...
