GaN Ku-band low-noise amplifier design including RF life test
Sara D'Angelo,Andrea Nalli,Davide Resca,Antonio Raffo,Corrado Florian,Francesco Scappaviva,Giorgio Vannini,S. Rochette,J.-L. Muraro +8 more
TL;DR: In this paper, the authors describe the design and characterization of a Ku-band monolithic microwave integrated circuit low-noise amplifier for telecom space applications, exploiting an industrial aluminum gallium nitride (AlGaN)/GaN high electron mobility transistor (HEMT) on silicon carbide process.
Book ChapterDOI
Nonlinear Embedding and De-embedding: Theory and Applications
TL;DR: In this article, two recently proposed characterization techniques of microwave transistors oriented to high-frequency power amplifier (PA) design are discussed, along with evidence of their advantages with respect to conventional design approaches in terms of power and frequency handling capability.
Proceedings ArticleDOI
High-efficiency broadband power amplifier design technique based on a measured-load-line approach
TL;DR: An innovative power amplifier design technique oriented to microwave applications which require both high efficiency and large bandwidth is presented, based on a recently proposed technique which achieves the same level of accuracy provided by expensive nonlinear setups operating at microwave frequencies.
Proceedings ArticleDOI
An Ultra-Wideband Setup to Monitor Antenna-Impedance Variations in Low-Cost IoT Transmitters
Alessandra Petrocchi,Antonio Raffo,Gianni Bosi,Giorgio Vannini,K. Yavuz Kapusuz,Sam Lemey,Hendrik Rogier,Gustavo Avolio,Dominique Schreurs +8 more
TL;DR: An innovative ultra-wideband setup to detect real-time variations in antenna impedance in transmitters oriented to Internet of Things and 5G applications is presented and validated by means of multi-tone measurements at microwave frequencies.
Journal ArticleDOI
Nonlinear modeling of InP devices for W-band applications
Davide Resca,Valeria Di Giacomo,Antonio Raffo,Rafael Cignani,Alberto Santarelli,Giorgio Vannini,Fabio Filicori,Dominique Schreurs,Farid Medjdoub,Nicolas Thouvenin,Christophe Gaquiere +10 more
TL;DR: In this paper, a distributed modeling of extrinsic parasitic effects in electron devices is used for the very first time in conjunction with a lumped equivalent circuit model for the intrinsic device.
