Abstract
AbstractA reliable modeling procedure is developed for extracting an equivalent circuit able to reproduce the small-signal and noise performance of the gallium nitride (GaN) high-electron mobility transistor (HEMT) technology. The main advantages of this model are its simplicity and straightforward extraction based on only pinch-off scattering (S-) parameter measurements. The validity of the achieved model is verified by the good agreement between high-frequency experiments and simulations for three devices with different sizes. The model reliability is further confirmed by the observed good scaling of the extracted parameters. The same model is demonstrated by designing and simulating a broadband low-noise amplifier (LNA) for 5G applications.

Abstract
The photovoltaic solar potential in an urban sector and the effects produced by the electricity input into a low-voltage grid are determined, the analysis is performed for one year. First, the generation profiles are estimated, assuming the incorporation limits of typical silica panels and using photovoltaic (PV) tiles on roofs as an architectural alternative. Then, the consumer class demand is estimated. Production-demand matching is performed at the load point level to avoid impacts on the grid. A scenario incorporating a new load, induction heating cookers (IHCs) for all residential users, is posed, the use of which coincides with high-radiation hours. Finally, electrical storage is assumed to maximise the PV supply. A 16% coverage with silica PV panels, or 33% with PV tiles, would supply 46% or 39% of the consumption, respectively. With massive incorporation of IHCs and storage, the supply is increased to 73% and 59% of the consumption with silica panels and PV tiles, respectively. An annual consumption reduction of 16 Tn of liquefied petroleum gas is attained in the cases studied. Additionally, it is necessary to redirect the current subsidies for hydro dams and the overall energy sector towards promoting distributed microgeneration.
