Radio Circuits and Devices

Lecturer:

Pavel Kovář, Josef Dobeš

Tutor:

Pavel Kovář, Josef Dobeš, Štěpán Matějka, Pavel Puričer, Karel Ulovec

Supervisor:

Department of Radioelectronics

Synopsis:

The goal of the subject is to inform the students about properties, parameters, and design methodology of radio circuits, radio function blocks, and more complex blocks of radio transmitters and receivers. The lectures are devoted sequentially to elements, circuits, function blocks, and systems which are used at radio frequencies. The exercises are both seminar and laboratory; the seminars are devoted the basic calculations from the area of the radio function blocks, and the measurements are devoted to both basic function blocks and more complex problems from the area of radio transmitters and receivers.
