RF Power Amplifiers
Hrazděra, Tomáš ; Hubík,, Vladimír (referee) ; Šebesta, Jiří (advisor)
This work deals with high-frequency power amplifiers. In the theoretical part are briefly summarized the general characteristics and properties of particular working classes of amplifiers focusing on their efficiency. The next section is aimed on design of high-frequency power amplifier for 1296MHz band and its individual components. In this part is desribed design of hybrid combiners - splitters, directional couplers of the coupled lines, amplifiers with RA18H1213G module and power amplifier with transistor BLV958. The work also includes the results of simulations of designed circuit, realization procedure and the measured parameters of manufactured components. In conclusion of this work the theoretical and measured values are compared.
