“Designers of FMCW radar systems, microwave Point-to-Point communications and test equipment require high frequency solutions that are capable of operating in very high phase detector frequencies without any sacrifice in power consumption,” said Peter Real, vice president, Linear and RF Group, Analog Devices, Inc. “As the latest member of ADI’s leading family of PLL synthesizers, the ADF4159 represents an ideal solution for these applications by delivering best-in-class phase-detector frequency of operation and power consumption.”
Featured in Analog Devices Booth #1725, the ADF4159 Fractional-N PLL Synthesizer consists of a low-noise digital phase frequency detector (PFD), precision charge pump and a programmable reference divider. It can be used to implement frequency shift keying (FSK) and phase shift keying (PSK) modulation. There are also a number of frequency sweep modes available, which generate various waveforms in the frequency domain, such as sawtooth and triangular waveforms. The ADF4159 features cycle slip reduction circuitry, which leads to faster lock times, without the need for modification to the loop filter.
