Abstract
U ovom radu su opisani koraci dizajniranja F klase pojačala. Pojačalo je dizajnirano da tako da radi na frekvenciji od 2 GHz-a s ulaznom snagom od 5 dBm-a. Transistor je izmjeren i uspoređen s modelom u ADS-u. Simulacije u ADS-u su provedene bez dovoljno dobrih rezultata. Taj problem je riješen tako da se napravila posebna pločica na kojoj se mogla mijenjati impedancija na željenim harmonicima. Oblikovanje signala napona na drainu je postignuto s filterima i pomičnim kratkim spojem. Pokazano je kako različiti harmonici imaju utjecaja na oblik signala na drainu i poboljšanje svojstva pojačala snage.
Abstract (english)
In this thesis, steps in designing class F power amplifier were described. Amplifier is designed to work on 2 GHz with input power of 5 dBm. Transistor was measured and compared with its model in ADS. ADS simulation were carried out without decent results. To solve that problem, PCB with possibility of tuning was made. Waveshaping was done with filters and adjustable short circuits on second and third harmonic. It has been shown how different harmonics have impact on drain voltage waveform and improvement in PA's performance.
