Diseño e implementación de amplificadores de potencia en la banda de 12 a 20 Ghz, para el laboratorio de microondas de la FIE-ESPOCH.

Abstract

This Curriculum Integration Project aimed to design and implement power amplifiers in the 12 to 20 GHz frequency band to complement the microwave laboratory at FIE-ESPOCH. The goal was to facilitate student learning through practical exercises. The project involved a study of theoretical foundations to provide context on the origin and function of radio frequency power amplifiers in communications and telecommunications. Additionally, it explored technologies, materials, and designs applicable to their implementation. Power amplifiers were designed and implemented using monolithic microwave integrated circuit (MMIC) technology. The amplification modules used were PMA2-183LN+ and MAAM-011101. The circuit board design was executed using Proteus software, and surface-mount technology (SMT) was employed for implementation. Amplifier gains were determined by measuring the difference between the power of an unamplified test signal and the power output when the amplifiers were applied. The operational range was defined from 12 to 20 GHz, with measurements in 100 MHz increments. In amplification tests, an average gain of 15 dB was obtained for amplifiers constructed with PMA2-183LN+ modules, while amplifiers using the MAAM-011101 module demonstrated a gain of 7 dB. In conclusion, the amplifiers function as intended, providing gains within the specified operating frequencies.
