    • 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 ...
    • Accurate and process-tolerant resistive load 

      Sütbaş, Batuhan; Özbay, Ekmel; Atalar, Abdullah (IEEE, 2020)
      Resistive terminations cannot preserve high-quality matching at high frequencies due to the parasitic effects of the nonideal resistor. Moreover, resistance values of the termination resistors in integrated circuits are ...
    • Accurate isolation networks in quadrature couplers and power dividers 

      Sütbaş, Batuhan; Özbay, Ekmel; Atalar, Abdullah (IEEE, 2021)
      When quadrature couplers and power dividers are implemented in integrated circuits, accurate isolation networks can not be realized due to the nonideal resistors and the process variations. We present an isolation network ...
    • High efficiency 35 GHz MMICs based on 0.2 μm AlGaN/GaN HEMT technology 

      Akoğlu, Büşra Çankaya; Sütbaş, Batuhan; Özbay, Ekmel (Cambridge University Press, 2022-06-16)
      In this paper, two high efficiency monolithic microwave integrated circuits (MMICs) are demonstrated using NANOTAM's in-house Ka-band fabrication technology. AlGaN/GaN HEMTs with 0.2 μm gate lengths are characterized, and ...
