15 credits in spring semester
Teaching method: Laboratory, Lecture
Assessment modes: Coursework, Unseen examination

Radio Frequency (RF) circuits are the fundamental building blocks in a vast array of consumer electronics and wireless communication devices. Fibre optic communications is the backbone of the internet and enabler of mobile communication systems.

This modules provides insight into the principles of operation, and guidance to developing, RF circuit designs. It also covers fundamental principles and design of fibre optics. We draw on on industry-grade software tools and hardware and use a combination of theory and practice.

We teach key concepts of broad- and narrow-band small signal amplifiers, mixers and high-efficiency broadband power amplifier design. You also learn about the underlying mathematical models, complemented by PCB design, fabrication and laboratory implementation.

Topics covered include:

  • high-frequency devices and equivalent circuit models
  • coverage of electromagnetic transmission to millimetre wave and optical frequencies
  • the Smith chart
  • two-port systems
  • S-parameters
  • biasing
  • linearity
  • stability and matching
  • RF noise
  • RF circuits PCB software design
  • RF circuit PCB implementation and measurements
  • high-frequency measurements using vector network analyser
  • fundamentals and design of waveguides
  • fundamentals and design of optical fibres.

Pre-requisite

Analogue Communication and Propagation

Module learning outcomes

  • Apply fundamental knowledge and principles of radio to frequency (RF) and optical circuits to design of RF circuits, waveguides and fibre communication networks.
  • Analyse and design RF circuit matching networks using Smith Charts
  • Perform stability analysis of RF two-port systems and design stable and low-noise RF amplifiers
  • Use software laboratory, industry-grade PCB design tools and HW prototyping appropriate programming language to design and evaluate low-noise RF amplifier circuits.
