Course Outline and Policy

Description

This course is designed to train the students to RF circuits & systems design techniques for radio communications leading towards the recent research in the domain of advanced radio technology. In the first half of the course, the students will be exposed to the fundamental concepts of passive and active circuits design at radio frequencies. These fundamental concepts require substantial understanding of transmission line theory and Smith chart and therefore this course will start with thorough discussion on these two topics. This also includes training the students on the commercial software tools such as Advanced Design System (ADS), CST Microwave Studio, and Keysight SystemVue. Tutorials on these tools will be provided. Eventually, the design assignments will train the students on advanced features of these tools.

Postconditions On the completion of this course the students will be able to:
1. Learn various RF Circuit design techniques.
2. Acquire hands-on skills to analyze and design simple components, such as matching networks, coupler, power divider etc, used in the Radio Communication Circuits.
3. Gain skills in using at least one of the software tools ADS/CST/SystemVue, PCB Printing Machine, and RF Instruments such as Vector Network Analyzer, Spectrum Analyzer, and Power Sensor.
