    • Design of an X-band GaN based microstrip MMIC power amplifier 

      Özipek, Ulaş (Bilkent University, 2019-02)
      RF power amplifiers are crucial components of modern radar and communication systems. However, their design poses some challenges due to device limitations in high power and high frequency regime, as well as inherent ...
    • GaN based LNA MMICs for X-band applications 

      Zafar, Salahuddin; Osmanoğlu, Sinan; Öztürk, Mustafa; Çankaya, Büşra; Yılmaz, Doğan; Kashif, A. U.; Özbay, Ekmel (Institute of Electrical and Electronics Engineers, 2020)
      In this paper, we report two low noise broadband amplifiers based on ABMN's AlGaN/GaN on SiC HEMT technology for X-band applications. Two design topologies, a single-stage (LNA-1) and a two-stage (LNA-2), have been ...
    • A high gain and high efficiency 15 W X-Band GaN power amplifier MMIC 

      Gürdal, Armağan; Özipek, Ulaş; Sütbaş, Batuhan; Özbay, Ekmel (IEEE, 2019)
      An X-band microstrip power amplifier MMIC based on our 0.25 μm AlGaN/GaN on SiC process technology is presented in this work. Fabrication steps, HEMT structure and typical device performance are demonstrated. Design procedure ...
    • Metamaterial Absorber Based Multifunctional Sensor Application 

      Ozer Z.; Mamedov, Amirullah; Özbay, Ekmel (Institute of Physics Publishing, 2017)
      In this study metamaterial based (MA) absorber sensor, integrated with an X-band waveguide, is numerically and experimentally suggested for important application including pressure, density sensing and marble type detecting ...
