Digital device for supervising and evaluating outdoor activities
Pecen, Vojtěch ; Macho, Tomáš (referee) ; Petyovský, Petr (advisor)
This project deals with development of portable electronic device which brings new opportunities to leisure activities and their evaluating. At first, analysis of devices available on market and their acquisitions is made, then tips and ideas of new activities, which would be played with digital devices, summation of features, that the device would do, choosing adequate components, their assembly, configuration and programming. After it, domonstration of the device is described and this document is summarized.

Solid State Power Amplifier for the L-Band
Pecen, Vojtěch ; Vondra, Vlastimil (referee) ; Kasal, Miroslav (advisor)
The goal of this diploma's thesis is to create a design of a two stages amplifier working in a band reserved for the secondary surveillance radar at the frequency of 1090 MHz. Output power of the amplifier should be 20 W and efficiency should be as high as possible. Because of this the second stage is designed in class C. Contents of this diploma's thesis include a theoretical analysis, simulations of the amplifier parameters, comparison of the Ansys Designer and AWR Microwave Office simulation programs and design of both stages of the amplifier, followed by a comparison of the measured parameters with the simulations.

Microwave power amplifier
Pecen, Vojtěch ; Urbanec, Tomáš (referee) ; Kasal, Miroslav (advisor)
The goal of this bachelor's thesis is to create a design of a microwave power amplifier working in X-band at the center frequency of 10.368GHz. The amplifier has to operate in CW mode and pulse mode with output power of 36dBm and gain of 20dB. Contents of this bachelor's thesis include a theoretical analysis, design of the amplifier and its bias and protective circuits, simulations of time constants of the bias circuits, simulations of the amplifier, construction and measurement of the amplifier parameters.
