Power amplifier for 435MHz Band with High Efficiency
 Herceg, Erik ; Špaček, Jiří (referee) ; Urbanec, Tomáš (advisor)
This diploma thesis is focused on design of high frequency power amplifiers in UHF band, specifically at 435 MHz. Amplifiers are designed in different classes of operation. The thesis deals with the comparison of main parameters in each class of operation, the most important parameter is effeciency. The amplifying part is unipolar transistor which is working in Single-stage mode. The results were simulated in Advanced Design Systems Software.

Intrinsic And Extrinsic Parameters Of Galium - Nitride Transistors
 Herceg, Erik
This article deals with the extrinsic and intrinsic parameters of the Galium-Nitride RF transistor. These parameters are essential in any design of large-signal analysis of RF amplifiers. Package parasitics are the biggest problem of integrated circuits (ICs), especially at high frequencies. Each IC package gives unwanted parasitics to the primary function of the IC. The analysis of these package parasitics can be performed by the transistor manufacturer, which provides a non-linear model of the transistor, where parasitics elements are separated from the transistor. With these separated package parasitics, the highest efficiency, power output, and accurate harmonic termination can be achieved. The main purpose of this article is to describe these problems.
