Frequency synthesizer for microwave communication systems
Klapil, Filip ; Vondra, Vlastimil (referee) ; Kasal, Miroslav (advisor)
The main aim of the thesis is to develop a solution of a frequency synthesizer for a microwave communication systems. Specifically, it suggests a design for frequency synthesizer with phase-locked loop. At beginning of the thesis the principle and basic properties of this method of signal generation are explained. Then it is followed by a brief discussion of the parameters of synthesizers and their influence on design. Another part of the work is the analysis of circuit the frequency synthesizer with the phase-locked loop MAX2871, which is followed by a proposal for the design of the frequency synthesizer module hardware. The last part of the work deals with practical implementation, verification of function and measurement of achieved parameters and their evaluation.

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.
