Dual band power divider for GSM(900/1800)
Elfmark, Zdeněk ; Fiala, Pavel (referee) ; Šporik, Vladimír (advisor)
he work deals with different types of Wilkinson Power Divider suitable for band GSM (900/1800). In the thesis is talking about three types and contains the brief descriptions of their functions. It is mentioned their connection and the most important components of each types. All dividers are presented by form of simulation. The aim of this thesis is design and realizes a dual band Wilkinson Power Divider, using planar or SMD technology.

Power supply for space application
Hrubý, Lukáš ; Bohrn, Marek (referee) ; Pavlík, Michal (advisor)
The following work deals with a design of switched mode power supply. In this essay, there is detailed description of non-isolated and isolated topologies of SMPS, used in industry. Next, there are calculations for design and analysis which are needed for space design. There will also be selected devices, which could be used in final device. Based on experience and ECSS requirements, there will be chosen parameters of SMPS, which could be then used as a module for future space design. Chosen topology of SMPS will be created as engineering model assembled with commercial components. One part of this work is dedicated to design and realization of planar transformer and coupled inductor.

Multiple Output Power Supply Module
For Space Applications
Hrubý, Lukáš
The purpose of this article is to describe design and implementation of multiple output power supply unit. Main goal is to create forward converter with cross-coupling of output lines, which would significantly increase the accuracy of output voltages under different load conditions. As almost every isolated DC-DC converter needs a transformer, there will be a short introduction on how to design and create one utilizing planar technology. For further puproses, this power supply will be designed with respect to requierements which are derived from ESA standards. Whole power unit will be fitted into box designed for mounting on spacecraft.
