Radio-frequency mixer
Kolář, Jan ; Urbanec, Tomáš (referee) ; Dřínovský, Jiří (advisor)
This bachelor's thesis is aimed to describe main parameters of mixers and principle of their measurement. There are presented devices and methods by whitch mixers can be measured. There are mentioned typical values of these parameters. The realisations of mixers are also described in this bachelor's thesis. The realisation is focussed on particular parts and circuit design. The part of this thesis is aimed to construct a working mixer and to measure its parameters. Also there is mentioned a design of laboratory exercise and an automated measurement setup done in Agilent VEE.

Business Plan - Biogas Plant
Michalica, Miroslav ; Kolář, Jan (referee) ; Veselý, Josef (advisor)
The subject of the thesis is to design a business plan for the construction of biogas plant in the village Bulhary. The actual work is divided into two main parts. The first part is devoted to theoretical resources of a business plan and theory related to biogas station. The practical part of the thesis applies the theoretical knowledge to create a real business plan.

Power Line Communication Simulator in Network Simulator-3
Kolář, Jan ; Fujdiak, Radek (referee) ; Mlýnek, Petr (advisor)
This thesis deals with the powerline communication focusing on the simulations of channel transfer functions. The introduction summarizes basic information about PLC followed by the analysis of the available PLC Software simulator (implemented in NS-3) and the analysis of implemented noises and interferences and its extensions. One chapter is devoted to possibilities of link capacity calculation. Within the thesis, various methods of calculation of primary parameters of transmission line were implemented and the simulator was compared with other freely available simulators. Subsequently, simulations were carried out focused on channel transfer functions in different topologies, on the impedance changes of branch, on the lengths of branch, and changes in the direct path between communicating nodes.

L-band receiver front-end
Kolář, Jan ; Špaček, Jiří (referee) ; Kasal, Miroslav (advisor)
This Master's Thesis deals with a design of L-band receiver front-end. In the concrete the receiver is designed for receiving signals of frequency band 1,3 GHz. All particular blocks from low noise amplifier to intermediate frequency amplifier and frequency doubler in LO input are described, designed and simulated in program Ansoft. The part of this Master's Thesis is aimed to construct a working front-end receiver and to measure its basic parameters.

Partial reconfiguration methods based on programmable structures
Kolář, Jan ; Kváš, Marek (referee) ; Valach, Soběslav (advisor)
This master's thesis dissertates of partial reconfiguration methods based on programmable structures. In theoretical part it deals with difference and modular-based method of Xilinx's FPGAs Partial reconfiguration. Options of both reconfiguration techniques were written for Spartan 3, Virtex II, Virtex 4 and Virtex 5 processors. Diference-based method was in practical part tested on Spartan 3E Starter Kit and modular-based on ML501 board. All configuration bitstreams are included on CD. Xilinx Inc. provided all needed software tools such as ISE9.2i and PlanAHEAD.
