Radio TechnologyLaajuus (4 ECTS)

Objective

After completion of this course the student will be able to understand the significance of polarization and the properties of the media in the radio channel. The student will be able to design and analyze microstrip lines. The student will understand the significance of the refelections and matching in high frequency circuits. The student will understand the operation of the phase locked loop and its most common applications. The student will understand the most important properties of antennas and know the most common antenna structures. The student will know the most common active and passive high frequenct componets and understand their operating principles.
After completion of this course the student will be able match a complex load impedance to the real generator impedance by lumped elements. The student will be able to design a simple radio receiver and a simple frequency synthesizer in block diagram level. The student will be able to connect and measure the properties of a simple radio receiver. The student will be able to use a spectrum analyzer to measure signal spectra and a network analyzer to measure the frequency responses and impedances of RF amplifiers and filters.
