Abstract :
In this paper, the Settling time of PLL are analyzed. Present a Millimeter-Wave Frequency Agile Synthesizer based on PPL with DDS interpolated; add the module of VCO voltage presets to changing the settling time controlled by MCU and DAC. Using this scheme, the frequency synthesizer is designed, and its output signal at the frequency range of 35-36Ghz with step of 10MHZ, Frequency-hopping time<;1us, and the phase noise performances in the above frequency range are better than -80dbc/hz@1khz.
