Laboratory High-Frequency Generator
 Konzal, Jan ; Záplata, Filip (referee) ; Šebesta, Jiří (advisor)
This thesis describes a proposal of laboratory high frequency generator based on the principle of indirect analogue synthesis with a phase sling. The first part of the work describes the principle of a direct numerical and indirect analogue synthesis. Frequency range of the designed generator is up to 900 MHz. The output of the generator is designed to be up to 12dBm. Output impedance is 50 . To reach a frequency of oscillation lower than 800 MHz, the principle of fusion is used. Further, the control was suggested to be carried out by a microprocessor. Operating is realized using a keyboard and a rotary encoder.
