IL2219 Radio Electronics 7.5 credits

This course aims at familiarizing the student with modern radio electronic devices, circuits and systems and to provide a relevant background to the common mobile applications standards of today. A focus will be put on knowledge of integrated radio circuit building blocks so that at the student at end of the course is well equipped to pursue either an industrial or academic career in the area. The course will prepare the student for diploma thesis work in the area of Radio Electronics, as he will be further trained in circuit design beyond the knowledge gained in analog courses. The most important CMOS and bipolar techniques for low power applications will be studied for radio applications and modern design tools will be used.

Content and learning outcomes

Course contents

The course starts with an introduction to radio electronics and continues with basic concept as noise, non-linearity, sensitivity, etc. Then, modulation and access-methods are discussed and be given an overview of industrial standards of today. Different receiver-architectures that the heterodyne, the homodyne, image-reject, digital-IF, and subsampling be gone through and also transmitter architecture. Furthermore, the course explains certain passive circuits, transmission lines, S-parameters, Smith charts. Building blocks appropriate for radiocircuits are discussed. Low noise amplifiers and mixers in both CMOS and bipolar design. Here, adaptation and noise characteristics are also discussed. Oscillators with phase noise, pulling and injection-lock are explained as well as synthesizers with different phase-lock structure. The course is completed with power amplifier and linearisations techniques.

Intended learning outcomes

After passing the course, the student shall be able to

  • give an account of modern radio implementations with an emphasis on radio components, radio circuits, radio systems, and special building blocks appropriate for integration on chip

in order to be prepared for degree projects in the field and furthermore industrial or academic careers.
