Abstract:
With the rapid development of mobile communication test equipment, it is the difficulty of the design that is wideband high performance frequency synthesizer. A high performance frequency synthesizer is designed by using double PLLs and fractionalN based on SigmaDelta technology in this paper. A 2 000~4 000 MHz frequency coverage is implemented. A frequency resolution is less than 0.03 Hz. The phase noise level is less than 105 dBc/Hz@10 kHz in band. The test result meets the design requirements of wideband high performance frequency ynthesizer It has a high practical value.
Key words: frequency synthesize, PLL, VCO, frequency mixing
