Course design
The course treats analysis and design of microwave circuits, particularly amplifiers but also oscillators and nonlinear circuits like mixers and multipliers.
Topics: Two-port theory, impedance matching, stability, noise/gain optimisation, amplifier design, oscillation conditions, wideband amplifiers, the Bode-Fano criteria, high power amplifiers, microwave oscillators, mixers, multipliers, and nonlinear simulation techniques.
The course contains two lab exercises
- Design of a microwave-transistor amplifier using modern commercial soft-ware
- Assembly of the designed amplifier and measurement to verify the simulated performance
The course contains two home assignments
- Design of a noise optimized small-signal amplifier
- Exercise in large-signal modeling and nonlinear simulations, carried out in groups of 2

Be aware that all deadlines for home assignments and lab-preparations are sharp. A late home-assignment is not rewarded any points. On-time lab preparatory exercise is a prerequisite for doing the lab.
Learning objectives and syllabus
Learning objectives:
- Analyse two-port networks with respect to gain, noise, stability and VSWR
- Apply two-port representations for embedding, de-embedding and interconnecting components
- Apply equivalent transistor models for representation of microwave transistors
- Design and characterise a RF/microwave amplifier circuit (gain, noise, power, bandwidth, VSWR)
- Design a RF/microwave oscillator for low phase noise
- Extract small-signal transistor model parameters from S parameter measurements
- Extract large-signal transistor-model parameters from transistor DC characteristics and bias dependent small-signal S parameters
- Design and analyse nonlinear circuits such as mixers and frequency multipliers

Examination form
Successful completion of this course module is based on:
- Passed written examination (open book)
- Completion of two lab exercises
- Home assignment (amplifier design)
- Home assignment large-signal modeling and nonlinear simulations
Final grade is based on sum of results from home assignments (total 20p) and exam (total 60p): 3 (≥32p), 4(≥48p) and 5 (≥64p). The home assignments and the exam must both be passed individually, i.e., >4p on each home assignment and >24p on the exam
