Localization of RF transmiter
Mikuláštík, Jiří ; Burian, František (referee) ; Kopečný, Lukáš (advisor)
The thesis deal with possibility of localization of avalanche victims. Main focus is for RF avalanche beacons. The major objects of this thesis are design and construction of this device. A large part of thesis describes design of avalanche beacon and particular steps of realization. The design take into account the compatibility with commercial beacons. The paramters of designed device are verified by testing and measurement.

Shortwave power amplifier
Kufa, Jan ; Vařacha, František (referee) ; Prokeš, Aleš (advisor)
The aim of the master´s thesis is to create a high-frequency amplifier with switching power amplifier classes among classes A, B, C with output power of 10 W. The amplifier operates at frequency from 3.5 MHz to 14 MHz. Master´s thesis includes also theoretical analysis, design of lowpass filter and amplifiers and their simulation, mechanical realization and measured parameters of the amplifier.

Safety communicator
Kuřímský, Lukáš ; Boušek, Jaroslav (referee) ; Šteffan, Pavel (advisor)
The bachelors thesis deals with the draft of a safety communicator and the prototype that is able to transmit a rescue signal from areas that are inaccessible or not covered with GSM signal. The project offers a detailed description of the functions of the individual components necessary for processing and transmitting of the signal. Furthermore, it discusses the methods of transmitting and focuses particularly on one of the forms of amplitude modulation – amplitude shift keying that uses a self-healing protocol. It partly deals also with the process of choosing and designing the test antenna and its tuning.
