LINARES Y MIRANDA, R; GONZALEZ-JAIMES, H. E  y  LOPEZ-BONILLA, J. A DIDACTIC PROPOSAL FOR THE CHARACTERIZATION OF RADIO FREQUENCY DEVICES AND ELECTRICAL NETWORKS AT RANGE 100 KHz TO 500 MHz. Ingeniare. Rev. chil. ing. [online]. 2010, vol.18, n.3, pp. 295-301. ISSN 0718-3305.  doi: 10.4067/S0718-33052010000300003.

In this article a didactic outline of proof and measurement is presented for the characterization in frequency domain of components and linear circuits of radio frequency (RF). The outline is based on the observation of the temporary behavior shown by the incident and reflected tensions. These can be generated when RF sinusoidal signals are provided at ports and terminals of electrical networks or devices under study. The main goal of this paper is to propose an alternative experimental method that allows the study of phenomena normally addressed at the undergraduate level in various programs of Electrical Engineering or related disciplines. The method can be applied to subjects where topics related to the analysis of electrical networks are covered. It can also be applied to topics such as signal propagation in transmission lines, design and operation of antennas, and the fundamental principles of electromagnetic compatibility, among others.
