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. This will give a basic understanding of the radio receiver or the cellular phone but also the requirements put on the used circuits. Therefore this is a compulsory course for those who later want to specialise as radio frequency designers.

Contents:

  • 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, phase locked loops (PLL) and mixers
  • special components such as splitter, combiner, directional coupler and circulator
  • transmission lines, antennas, wave propagation and link budget
  • computer aided analysis
  • radio frequency measurements using spectrum and network analysers
  • analogue and digital modulation
  • a survey of modern digital communication systems
