Abstract :
The design principles of f-class amplifier of frequency range 5.8 GHz on the basis of composite right-left handed (CRLH) transmission line (TL) are developed. The structure (fig.1) uses two open CRLH tuners for the suppression of the second, the third, the fourth and the fifth harmonics, and the fundamental frequency has been matched at 50 ohms. The characteristics of 16QAM (64QAM) system with the use of designed amplifier are investigated.
