      Cengiz, Ömer; Kelekçi, Özgür; Arıkan, Galip Orkun; Özbay, Ekmel; Palamutçuoǧullari O. (IEEE, 2011)
      This paper reports two different S band GaN MMIC PA designs for WiMAX applications. First PA has a 42.6 dBm output power with a 55%PAE @ 3.5 GHz and 16 dB small signal gain in the 3.2-3.8 GHz frequency range. When two of ...
    • 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 ...
