Implementación de un set de multiplicadores de frecuencia para las bandas C, X y Ku de alta frecuencia utilizando tecnología MMIC para el Laboratorio de Comunicaciones y Microondas en la FIE-ESPOCH.

Abstract

The implementation of a set of frequency multipliers for high-frequency C, X, and Ku bands by using a Monolithic Integrated Microwave Circuits (MMIC) technology for the Laboratory of Communications and Microwave at the School of Computer Science and Electronics of the Escuela Superior Politecnica de Chimborazo (FIE-ESPOCH). The project was developed to contribute and complement the knowledge acquired in the classrooms by performing laboratory practices that benefit the teaching and learning processes of students and teachers of the School of Telecommunications Engineering of the FIE-ESPOCH. The set of frequency multipliers X2 KSX2-24plus, X3 RMK-3-123plus, and X5 RMK-5-83plus with MMIC technology was implemented with nine devices that operate in the order of microwaves, including C, X and Ku bands at frequencies from 4 to 8 GHz, 8 to 12 GHz, and 12 to 18 GHz respectively. The designs of the tracks of the frequency multipliers were made in the Ansoft Designer Software, the material chosen for the implementation of these designs is Roger RO4003C, dielectric used in high frequencies. The designs of the tracks of the frequency multipliers were modified at the input and output ports in its three models in particular X2, X3, and X5; due to the need to make a 50 ohm coupling so that it fits correctly with the subminiature version A (SMA) connectors that are located at the ends of the device. The printing process of the tracks on the material was carried out by photo rebelling. The multipliers work not only in their multiplicity but in the other harmonics allowing greater operability.
