Abstract :
This paper proposes a design of a PLL frequency synthesizer for LTE wireless channel simulator. A triple-VCO is used in the single-loop PLL to design the broadband and miniature frequency synthesizer. The bandwidth is from 2.8GHz to 6GHz. Test results show that, in the offset frequency of 10kHz from the carriers, phase noises are -108.95dBc/Hz@3GHz, -103.94dBc/Hz@4GHz, -99.17dBc/Hz@5GHz and -94.32dBc/Hz@6GHz.
