What experience do you have with RF design and analysis?

Sample answer to the question

I have some experience with RF design and analysis. During my time as an electrical engineering intern, I had the opportunity to work on a project that involved designing and testing an RF circuit. I used RF design software to simulate the circuit performance and made improvements based on the simulation results. I also assisted in the lab testing of the circuit using oscilloscopes and spectrum analyzers. Overall, I have a basic understanding of RF principles and testing methods.

A more solid answer

I have experience with RF design and analysis in both academic and professional settings. In my senior year of electrical engineering, I worked on a team project where we designed and analyzed an RF communication system for a drone. We used CST RF Studio software to simulate the system and optimize its performance. I also gained hands-on experience in the lab, using oscilloscopes, spectrum analyzers, and network analyzers to test and validate our design. Throughout the project, I collaborated closely with software engineers to ensure the integration of the RF system with the drone's control system. I documented our design processes and results in technical reports, which were used for reference in future iterations. To stay updated with the latest RF technologies and advancements, I regularly attend webinars and participate in online courses.
