Controll Module for Circuits with ADF4360 and Selected DDS
Lambor, Jiří ; Vágner, Petr (referee) ; Urbanec, Tomáš (advisor)
This bachelor’s thesis is focused on issues of communication between microprocessor unit and frequency synthesizer circuits - direct digital synthesis circuit (DDS), voltage control oscillator with phase lock loop (ADF). The basic theoretical function of DDS, ADF and SPI interface is described in the introduction. The solution and drafts of modules hardware are shown in next chapter. Last chapter describes programming of DDS and ADF circuits with examples of this code in C language. Schemes and board layouts of modules are attached in appendix.

Experimental wireless link in frequency band 60 GHz
Lambor, Jiří ; Polívka, Milan (referee) ; Raida, Zbyněk (advisor)
This thesis is focused on a wireless link operating in 60 GHz frequency band. In this band, the attenuation due to resonance of oxygen is high. Thanks to this property, we are able to ensure a proper insulation of communication links working in two close bands. The document compares commercially available modules of offered by different manufacturers for the operation in this band. The design, the simulation and the fabrication of a antenna and its feeder are described in the next part of the thesis. The system is fabricated using a SIW technology.
