Tiivistelmä
The topic of this thesis belongs to the broader research project at LUT University during year 2024. The research project focuses to the DFMA and sustainability analyses of more than 40 different MW and RF components. The results of this thesis will be utilized later to build an overall picture of the DFMA and sustainability aspects related to MW and RF technology.
In this thesis, it aimed to develop a manufacturing plan and select suitable materials for waveguide switches in the 18-26 GHz band, ensuring device performance and stability in harsh environments. The approach involved literature review, expert interviews, SolidWorks modelling, and systematic material selection. A key outcome was the selection of oxygen-free copper for its electrical conductivity, crucial for signal transmission within the specified frequency band. Despite its lower corrosion resistance compared to certain alloys, surface treatments significantly enhanced its durability. The study also addressed manufacturing challenges like dimension and geometric tolerance settings, contributing theoretical and practical insights to the mechanical engineering field, especially in microwave device manufacturing, and paving the way for future research.
