Fachpraktikum

Microwave Circuit Design: CAD & Lab

The course serves to deepen practical knowledge in the field of analog microwave front end design. The exemplary design cycle includes the CAD-software aided simulative circuit design as well as the metrological characterization of circuit components in the laboratory.

IMPORTANT INFORMATION
The lab course 'Microwave Circuit Design: CAD & Lab' will be offered as on-site course with physical presence of students on the premises of ILH. The central hygiene concept of the University of Stuttgart will be applied. The lab course takes place as weekly event during the lecture term from October to February. The lecturer reserves the right to change the mode of organization in order to comply with the prevailing frame conditions for on-site courses.

Goals

The aim of this Fachpraktikum is to deepen theoretical knowledge in the fields of high-frequency circuit design and analog circuit design. For this purpose, the design cycle of an analog microwave frontend for wireless point-to-point communication systems will be covered. Students will use a state-of-the-art CAD environment to design and simulate components of analog microwave frontends. In the laboratory, the metrological characterization of individual circuit components as well as the assembly and measurement of a wireless point-to-point data link is carried out.
Students with outstanding achievements receive the Keysight IndustryReadyCertificate at the end of the course.
