Abstract
This research project will explore the intricacies of Radio Frequency (RF) circuitry design, demonstrating acquired insights by constructing a discrete RF amplifier with digital input attenuation control. The study will delve into a multitude of RF topics such as serial communication, digital data storage, transmission line theory, impedance matching, network parameters, amplifier classes, and Smith chart analysis. The RF amplifier will be designed to have an approximately 15dB input gain/attenuation digitally controlled by an external microcontroller. The device will operate at 50 MHz, in the VHF frequency range, with an input and output impedance of 50 . A network analyzer will be used to facilitate thorough testing of prototypes and product functionality through its S-parameters. Final analysis will include measurement of gain and attenuation accuracy, efficiency, P1 dB linearity, amplifier PAE, total bandwidth, and K-factor. This learning endeavor will not only enrich understanding of RF and high-speed digital concepts and design strategies, but also provides hands-on experience in the design, construction, and testing of high frequency circuitry with digital controls.
Biography
Benjmain Cuebas is pursuing his BS in Electrical Engineering degree at Missouri University of Science and Technology via the Cooperative Engineering Program (CEP). He plans to graduate in 2025. He received his associate degree in electrical engineering from Ozarks Technical Community College in 2022. Benjamin has worked as an electrician and electronics technician during his pursuit of an EE degree and has always had a passion for electronics. In the summer of 2023, he did his first engineering internship, where he helped design test equipment for Monolithic Microwave Integrated Circuits and gained a new interest in the RF side of Electrical Engineering. He is a member of the CEP Embedded Systems club and the IEEE student club.
