Beam Shaping Circuits for L Band Antenna
Kalina, Ladislav ; Pítra, Kamil (referee) ; Urbanec, Tomáš (advisor)
This thesis contains design of beamforming network designed for passive radar antennas. The first part contains theory of passive radars and beamforming networks. The next part implies design of beamforming network at the block digram level. Then are choosed circuits for amplitude and phase control, including the design of control communication. It follows by realization of IQ phase shifter and his automatic measurement. Based on this results is phase shifter adjusted and PCB of 2x2 beamforming network is designed. Last part includes design of control application (Matlab) and control program for STM32F407VG microcontroller.

Audio mixer used for laboratory measurements
Kalina, Ladislav ; Šotner, Roman (referee) ; Kratochvíl, Tomáš (advisor)
This bachelor’s thesis deals with an analysis of the mixing console and its design. In several chapters are describes each parts of design. First part is focused on describing of mixing console, thereafter moving on the design each circuit such as preamplifier and equalizer. The second part contains design of printed circuit board and also measurement and testing those PCBs. This paper also including concept of chassis of whole device. Also contains graphic design of control panel.

Beamforming Circuits For L-Band Antenna
Kalina, Ladislav
This project describes the design of beamforming circuits for L-band antenna. The first part contains designed concept of a phase shifter. Other part consists block scheme of the phase shifter with real components and description of their basic functions. The next part implies theoretical calculation of possible settings. Last part includes realization of phase shifter and automatical measurement of circuit.
