Requirements

To pass the course, students need to collect points from various tasks, including homework submissions and a seminar report.There is no exam in this course.
Completion parts must belong to the same implementation

Learning Outcomes

After completing the course, student will understand the basic and some advanced RF circuit design concepts. Student will be able to analyze and design active RF circuits. For example, he or she will understand how a low-noise amplifier is constructed and how it operates; he or she is able to tell what each component is there for. In addition, student will have the ability to write a technical report dealing with some basic topic on RF circuit design and present its contents to others in a seminar.

Content

Content Core content Complementary knowledge Specialist knowledge
1. RF transistor amplifiers: Transistor modeling using linear circuit parameters (Y, Z, S and ABCD), small-signal equivalent circuits, and nonlinear ("spice") models. Stability (against oscillation). Impedance matching of two-ports, noise figure optimization, linearity.   Matlab RF toolbox, RF circuit simulations. Aspects in practical implementations.   
2. RF oscillator design: modeling an oscillator as 1) a positive feedback amplifier and 2) as a negative resistance device. Clapp-type (single transistor) and cross-coupled (two-transistor) oscillators. Frequency control using varactors (aka "varicaps" or "capacitance diodes") Crystal oscillators. Design rules-of-thumb and their origins.  Frequency stability, jitter and phase noise. DC-to-RF efficiency.   Oscillator design trade-offs and optimization.  
3. RF mixers: understanding mixer as 1) a circuit made of one or more switches 2) a circuit made of one or more nonlinear components. Active and passive mixers. Conversion loss/gain, mixing products (the wanted and unwanted output frequencies), linearity, port-to-port isolation.   Mixer noise figure.   
4.   Other active RF circuits: frequency dividers, prescalers, frequency multipliers, phase detectors, the phase locked loop (PLL), modulators, demodulators.    

Instructions for students on how to achieve the learning outcomes

- RF is "something else" but not difficult. This course makes it easy. - This course is very interactive. Students are encouraged to co-operate. Concepts are discussed in class until everyone understands them. - Students solve homework problems in the first period and prepare for their seminar presentation on the second period. According to student feedback, putting effort to homework and especially to own seminar paper is very educative and rewarding. - It is recommended (but not mandatory) that students take this course together with ELT-47286 RF Project. These courses support each other. - In this course English language has never been a problem to any nationality.

Assessment scale:

Numerical evaluation scale (1-5) will be used on the course
