    • A 6-18 GHz GaN power amplifier MMIC with high gain and high output power density 

      Sütbaş, Batuhan; Özipek, Ulaş; Gürdal, A.; Özbay, Ekmel (IEEE, 2019)
      A three-stage reactively-matched 6-18 GHz power amplifier MMIC design is presented. The design effort is focused on obtaining a low-loss output matching network for a high output power density. Active unit cells consist ...
    • High power K-band GaN on SiC CPW monolithic power amplifier 

      Cengiz, Ömer; Şen, Özlem; Özbay, Ekmel (IEEE, 2014-10)
      This paper presents a high power amplifier at K-band (20.2-21.2 GHz). The AlGaN/GaN CPW MMIC amplifier is realized with 0.25 μm HEMT process on 2-inch semi-insulating SiC substrate. The amplifier has a small signal gain ...
    • Novel predistortion algorithm for OFDMA 

      Ali, S.; Markarian, G.; Arıkan, Erdal (IEEE, 2009)
      The RF amplifier in a wireless communication system is usually non-linear in nature. If such an amplifier is used in OFDMA based systems, it will cause serious degradation. This degradation will be both in terms of the ...
