1 DEPARTMENT OF ELECTRONIC ENGINEERING MICROWAVE ENGINEERING 4 Year of latest revision: 2016 Semester 1

2 SUBJECT : MICROWAVE ENGINEERING 4 SUBJECT CODE : MCWE401 PREREQUISITE SUBJECTS : MICROWAVE COMMUNICATIONS 3 DURATION CONTACT TIME : One semester : 3 hours per week METHOD OF ASSESSMENT This course is based on cumulative assessment. There is no final examination. The final result is derived from the following: 1. One 3 hour open-book assessment counting for 30 marks, where the learner will be required to design a class A power amplifier to a given specification in the allocated time. This assessment will be an open-book assessment and computer simulation facilities will be available. 2. One 3 hour open-book assessment counting for 30 marks, where the learner will be required to design either an LC oscillator OR a crystal controlled oscillator to a given specification in the allocated time. This assessment will be an open-book assessment and computer simulation facilities will be available. 3. One 2,5 hour open-book written assessment covering all the course material and counting for 40 marks. This test will be written during the examination period. If a passing grade is not achieved for either assessment 1 or 2 a second opportunity will be given to students. If the specification for the assessment is met at the second opportunity the mark for the assessment will be recorded as 50%. If the specification is not met the original mark will be retained. Note that there is no second opportunity for assessment 3. PRELIMINARY ASSESSMENT DATES: Assess 1: Sat 19 March 2016: 08H30-11H30 2 nd opportunity Sat 02 April 11H30-13H30 Assess 2: Sat 07 May 2016: 08H30-11H30 2 nd opportunity Sat 14 May 11H30-13H30 Assess 3: Sat 28 May 2016: 08H30-11H00 No second opportunity COMMUNICATION BETWEEN LECTURER AND STUDENTS Communication between the lecturer and students after formal classes will be via dut4life accounts only. Students are expected to check their accounts on a daily basis. PURPOSE The purpose of this course is to reinforce the principles and techniques used in the design of high frequency circuits introduced in Microwave Communications III and to introduce the learner to non-linear RF circuitry including oscillators and power amplifiers.

3 COURSE NOTES An Introduction to RF Oscillator and Linear Power Amplifier Design, Revision 1 May 2015 Stuart MacPherson and Clive Whaits The course notes are provided. They are also available as a soft copy. COURSE SOFTWARE Extensive use is made of National Instruments AWR software for design and simulation in the course. The software is available in both computer rooms in the Communications Laboratory. Students are also expected to work with the software in their own time and are thus expected to download and install the software on their personal computers/laptops. The software licence is valid for the duration of the course. Instructions for downloading and installing the software follow.
