Aim

The course is intended to give a basic and wide knowledge in analysis and design of radio frequency (RF) amplifiers, based on lumped and distributed components, but also to provide engineering skills in measurement techniques that are necessary for verification of the result. The RF amplifier is an essential part in wireless applications such as cellular phones, multimedia terminals, computer networks, and short range communications between wireless devices.

There is a great demand for this knowledge as this technology area rapidly advances, primarily connected to implementation of systems för 5G and and millimetre wave radar.

Contents

The main focus is analysis and synthesis of high-frequency amplifiers. Systematic methods for the design of amplifiers with regard to optimum gain, stability, noise and output power are described. Circuits implemented with transmission lines and transistors in the frequency range MHz to THz are presented. Signal propagation on transmission lines is a natural topic since the wavelength of the signals often is comparable to the size of the circuit elements. Mesurement techniques based on advanced high frequency instuments such as spectrum and network analysers are important practical elements.

The theory presented in lectures is elaborated and practised in exercise seminars. The course comprises mandatory laboratory exercises where advanced measurement techniques are used to compare theoretical models with the behaviour of real components. The course also includes mandatory hand-in assignments.
