    Analysis and design broadband microwave distributed amplifiers
    (Çankaya Üniversitesi, 2017) Yurt, Reyhan
    In this thesis, microwave amplifier design techniques are analyzed and especially distributed technique is applied for broadband amplifier in L-S band according to the IEEE radar-frequency band. Conventional distributed amplifier (CDA) design topology is implied at 1-3 GHz frequency range. Available gain is obtained 14+2.5 dB with flatness. Optimum number of stages of amplifier is investigated and the result is evaluated as restriction of this topology so amplifier is designed with one stage. To increase gain performance cascaded single stage distributed amplifier (CSSDA) topology is analyzed and designed as 2-CSSDA at 1-3 GHz. In this design, almost 26 dB is obtained as peak value of available gain near 2.7 GHz and available gain is observed as 23.9+2 dB with simulations. CSSDA designed topology can be integrated with breakthrough circuit and approach so that more qualified distributed amplifier (DA) may be improved.
