Analog Devices' PLL Synthesizer Enables Flexible and Cost-Effective Radar Systems in Automotive, Aerospace,
Industrial and Communications Applications
- Feature-rich ADF4158 PLL synthesizer effective for FMCW radar systems, allows programmability and
configurability without dependence on VCO linearity; product is one-third cost of competitive devices.
26, 2009 -- NORWOOD, Mass.-- (EON: Enhanced Online News)-- Analog Devices, Inc. (ADI), a global leader in
high-performance semiconductors for signal-processing applications and leading provider of RF ICs (integrated
circuits), announced today the availability of its new
ADF4158 PLL synthesizer which enables flexible and cost effective implementation of FMCW (frequency modulated
continuous wave) radar systems. FMCW radar systems are used widely in automotive, aerospace, military, industrial
and communications applications to remotely measure the relative distance and speed of external objects. FMCW
radar systems can deliver detection and ranging at much lower power levels compared to traditional pulsed radar
approaches thereby offering a significant cost advantage.
FMCW radar systems require very high radio
performance and current approaches that rely on the linearity of the VCO (voltage controlled oscillator) pose a
number of design challenges due to their complexity, inflexibility, and high cost. The latest addition to ADI’s
industry-leading family of PLL synthesizers, the
ADF4158, is a 6.1GHz feature-rich and programmable device that can easily be configured to suit individual
FMCW radar system designers’ needs. Implementation of an FMCW radar system using the
ADF4158 produces a highly linear ramp profile that is completely independent of VCO linearity, thereby
improving radar resolution and reducing cost and complexity associated with system calibration. Furthermore, the
ADF4158 is based on dependable BiCMOS process technology to enable affordable implementations at one-third the
cost of competitive devices.
Additional ADF4158 Key Features and Benefits:
25-bit modulus allows sub-hertz frequency resolution • Frequency and phase modulation capability •
Generates saw-tooth and triangular waveforms in the frequency domain • Generates parabolic ramp •
Generates ramp with frequency-shift keying (FSK) superimposed • Generates ramp with two different sweep rates
• Ramp delay, ramp frequency readback and ramp interruption • 2.7 V to 3.3 V power supply • Separate VP
allows extended tuning voltage
