WebThis paper presents a low-power multi-modulus programmable frequency divider for a frequency synthesizer operating in the 19.25-20.25 GHz frequency band from a reference frequency of 40 MHz. The divider consumes 14 mW of power and is capable of producing divide ratios in the range of 481.25-506.25 with a fine resolution of 1 MHz. WebAs a side note, although the received signal is sampled at 150 MHz so the system can achieve the required range resolution, after the dechirp, you need to sample it only at a rate that corresponds to the maximum beat frequency. ... This example shows how to use FMCW signal to perform range and Doppler estimation in an automotive automatic ...
