Aim
The course is intended to give a general knowledge in radio frequency applications, especially those which are common in radio communications. The fundamentals are introduced without penetrating the electronics or design details. The different parts are treated as functional blocks defined by their physical properties rather than their electronic. This will give a basic understanding of the radio receiver or the cellular phone but also the requirements put on the used circuits. Thus Radio is a compulsory course for those who later want to specialise as radio frequency designers.
Knowledge and understanding
For a passing grade the student must
- have a good understanding of the radio receiver at a block diagram level
- be able to describe and analyse a modulated signal in the time, frequency and phase domain.
Skills and abilities
For a passing grade the student must
- be able to perform a noise analysis for a system under given circumstances
- be able to set up and apply a link budget for a radio system
- be able to perform basic measurements with spectrum and network analysers.
Judgement and approach
For a passing grade the student must
- be able to interpret a data sheet in order to design a radio system with basic modules, that fulfils a given specification.
Contents
Covered topics are
- basic concepts like bandwidth, Q-factor and decibel units
- noise sources, signal quality (SNR, SINAD), noise figure and noise temperature
- the structure of the radio receiver and transmitter
- the behaviour of discrete components at radio frequency, characteristics of amplifiers such as compression and intercept points, oscillators and mixers
- special components such as splitter, combiner, directional coupler and circulator
- transmission lines, antennas, wave propagation and link budget
- radio frequency measurements using spectrum and network analysers
- analogue and digital modulation
- a survey of modern digital communication systems.
Type of teaching:
The theory presented in lectures is elaborated and practised in seminars. At laboratory experiments advanced measurement techniques are used to study selected building blocks. The course comprises two mandatory laboratory exercises.
