This work presents a 2-decades wideband (15.5 MHz–1.55 GHz) low-noise amplifier (LNA) circuit. As its wideband range extends from HF to UHF, it includes, among others, the ISM bands (27.12 MHz, 40.7MHz, 434.79 MHz, 928 MHz), the GSM850 and GSM900 bands, and IEEE 802.22 WRAN bands (54 MHz–862 MHz). The proposed circuit operates also as a balun (single-ended input — differencial output) and its layout...
This paper presents the contamination levels, obtained applying the Equivalent Salt Deposit Density ESDD methodology in nine distribution circuits and five substations, belonging to ELECTRICARIBE S.A. E.S.P., and located in the north area of Barranquilla, the main Colombian Atlantic Ocean port. The paper shows the different study stages such as the sampling places selection and configuration, the...
