Impedance meter in the UHF Band using Reflectometry Techniques

This paper proposes the design and implementation of an impedance meter in the UHF band using reflectometry techniques. The device has the ability to measure the amplitude ratio and the phase difference of the reflected signal of a system under test with respect to an input signal. The main novelty...

En este trabajo se propone el diseño el implementación de un medidor de impedancia en la banda UHF mediante técnicas de reflectometría. El dispositivo posee la capacidad de medir la relación de amplitud y la diferencia de fase de la señal reflejada de un sistema bajo prueba con respecto a una señal incidente. La principal novedad propuesta es utilizar un detector comercial y, mediante un arreglo circuital implementado mediante técnicas de diseño en radiofrecuencias y procesamiento de señales, adecuarlo para que pueda medir en el rango completo de fase, distinguiendo el signo. Los valores adquiridos son procesados en una computadora para obtener la impedancia del sistema bajo prueba. application/pdf text/html https://elektron.fi.uba.ar/elektron/article/view/182 10.37537/rev.elektron.7.2.182.2023 spa FIUBA https://elektron.fi.uba.ar/elektron/article/view/182/337 https://elektron.fi.uba.ar/elektron/article/view/182/344 Derechos de autor 2023 Brian Maximiliano Gluzman, Facundo Alekseenko, Ramiro Avalos Ribas, Alejandro José Uriz, Jorge Castiñeira Moreira Elektron Journal; Vol. 7 No. 2 (2023); 77-83 Revista Elektron; Vol. 7 Núm. 2 (2023); 77-83 Revista Elektron; v. 7 n. 2 (2023); 77-83 2525-0159 2525-0159 Impedance Meter Amplitude and Phase Detector UHF Impedancímetro Detector de Amplitud y Fase UHF Impedance meter in the UHF Band using Reflectometry Techniques Impedancímetro en la banda de UHF mediante técnicas de reflectometría info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://repositoriouba.sisbi.uba.ar/gsdl/cgi-bin/library.cgi?a=d&c=elektron&d=182_oai
