Power amplifier for 2 metres radio amateur transmitter
 Klapil, Filip ; Vařacha, František (referee) ; Prokeš, Aleš (advisor)
This work deal with development a solution of a power amplifier for 2 metres radio amateur transmitter with a minimum output of 1 kW. Part of the solution is to use a commercial module of power amplifier. In addition, the design of the input attenuator, the switching elements in the signal path, the output filter and the protection circuits including cooling. The bachelor thesis contains a proposal of a system solution with a discussion of required performance and legislative requirements. This is followed by a hardware section, where the work is devoted to the design of the hardware, the theoretical calculation of the components and the simulation. In the last part of the work deals with practical implementation, verification of function and measurement of achieved parameters and their evaluation.
