High frequency techniques 1 IS-FEE-10033

The aim of the course is to acquaint the students with basic topics of high frequency techniques: components, instruments, measurements, applications. Training skills of calculation of voltages and currents in transmission lines and solving simple problems of impedance matching.
Examples of applications of high frequency devices and systems. Electromagnetic waves in transmission lines (coaxial lines, striplines, microstrips) and in waveguides. Wave types (TEM, TE and TM) and wave modes. Definitions of current, voltage, characteristic impedance. Impedance matching (narrowband and broadband). The Smith chart. Multiport circuits. The scattering matrix. Passive microwave elements: reactance irises, matched loads, stub tuners, attenuators, phase shifters, power dividers, hybrid junctions, directional couplers. Resonators. Ferrite devices. Semiconductor devices. MEMS. Basics of high frequency measurements. Network analyzers.

Requirements:
Circuits and Signals, Electromagnetic Field Theory.
