Design and realization of switching class audio power amplifier
Levocký, Kristián ; Götthans, Tomáš (oponent) ; Brančík, Lubomír (vedoucí práce)
This bachelor thesis describes design of audio amplifier of class D with power 2x100W. Power part is designed with integrated circuit TAS5630B made by Texas Instruments and correction preampifier unit is regulated by four potentiometers , controled by integrated circuit TDA1524A. Switching supply is regulated by circuit TOP261EN. Whole device is installed in device box with graphic display and control components.

60GHz omni-directional antenna
Levocký, Kristián ; Pítra, Kamil (oponent) ; Mikulášek, Tomáš (vedoucí práce)
This thesis deals with brief research on problematics of antennas in microwave band for omni-directional applications, own design and assembling of such an antenna. The purpose of the design is to have a best possible radiation patterns and reflection loss of our antenna. Conical monopole is chosen and it is simulated and changed to get the best possible parameters. Two prototypes are manufactured with mechanical changes applied and their parameters measured. Finished antenna is used for experimental channel measurement.

Omni-Directional Antenna For 60 Ghz Band Chan-Nel Measurment
Levocký, Kristián
This paper describes a design of an omni-directional antenna for a 60 GHz band. A monoconeantenna is integrated with a mm-wave coaxial connector. Such a structure is small in sizeand provides an omnidirectional radiation pattern with a wide vertical angle. The paper pre-sents acomparison of simulated and measured results of a fabricated prototype. The antenna is in-tendedto be used for mm-wave channel measurement.
