Overview

The Institut für Hochfrequenztechnik und Elektronik (IHE) is glad to offer Workshop angewandte Hochfrequenztechnik course for bachelor (B.Sc.) students in the coming winter semester 2020-21. The students can attain 3 ECTS upon successful completion of the laboratory course. The laboratory provides a unique opportunity to the students for strengthening their practical knowledge of RF systems and learning basic RF measurement techniques. The course consists of 3 experiments in total and each experiment is divided into 1-2 afternoons (4 hours each). The experiments range wave propagation over single RF circuit and each of these experiments is accompanied with either design and simulation using tools like CST, Matlab etc or using state-of-the-art measurement equipment like spectrum analyzer, network analyzer etc.

 

Guidelines for Students

The Students will be divided into groups of 2 students per group and the group allocation will be finalized by the laboratory supervisor on the laboratory introduction day on 03.11.2020. Only those students who are present on the laboratory introduction day will be finally registered for participation in this course. The group plan and laboratory schedule will be uploaded on this webpage on the same day. The students should check the laboratory schedule and find the order of experiments allocated to their specific group. Each experiment is accompanied with a script (available on this webpage) which will help students in reviewing the key concepts involved in that particular experiment.

The first experiment will take place on 10.11.2020. The venue will be updated soon.

 

Laboratory Evaluation

For successful completion of this laboratory course, it is mandatory for each student to

  1. Submit the laboratory homework (individual submission) before starting the experiment
  2. Score at least min. passing mark in the written/oral test conducted before every experiment. If a student fails to pass the test, he/she will not be allowed to conduct the experiment. In this case they should fix a new appointment with the experiment supervisor, re-appear for the test.
  3. Submission of experiment protocol (one protocol per group) at the end of each experiment.

 

Prerequisite

The students should have basic knowledge of RF concepts and minimum level MATLAB programming skills for undertaking the laboratory.

 

Registration

If your student account is managed under the CAS Campus system, then you should enroll yourself in https://campus.studium.kit.edu/ External Link for Microwave Laboratory WS 2020-21. If your student account is managed under the HIS-POS system, then you should collect the „Zulassungsbescheinigung“ (Blue Sheet) from HPA/MPA (Bldg. 30.36, Room No. 208) and submit it to Ms. Sevda Abadpour (Bldg. 30.10, Room 3.28).

Start date: 27.09.2020

End date: 11.10.2020

Please note that we have limited places available in the Laboratory (max. 12) and therefore only the first 12 Students who enroll themselves either in https://campus.studium.kit.edu/ External Link or by submitting the blue sheet will be registered for participation in the Laboratory.

 

Introduction

A brief introduction of the laboratory will be given on 03.11.2020, at 09:00 via  Teams meeting.

Attending the introduction is compulsory for all the students. If you fail to attend the introduction on 03.11.2020, your place will be given to the next student in our waiting list.

 

Groups 2020-21

 

Topics

1. Measuring planar waveguides modes and standing waves (pdf)

Supervisor: Yueheng Li

Venue: IHE, building 30.34 , room 1.11

In this part of the laboratory, the field strength of the first propagating mode in planar waveguides is measured for different conditions combining theory with hands-on experiences

 

 

2. Microwave and RF Measurements: Characterization of a Microwave Transceiver (Script, Homework)

Supervisor: Sevda Abadpour

Venue: Room 1.31, IHE building 30.10

The aim of this course is to understand the functionality of microwave measurement equipment such as signal generators, spectrum analyzers and vector network analyzers, as well as to learn the handling of this equipment. During the two exercises these microwave measurement instruments are used to characterize microwave devices such as amplifiers, mixers, filters, oscillators and a full transceiver circuit.

During the preparation phase for this laboratory exercise please solve the following home work (pdf). You will be asked to show the solution to your supervisor before starting the laboratory.
