Crystal Oscillators for Millimeter-Wave Radar

Millimeter-wave radars require chirp clock crystal oscillators with wide-temperature adaptability and ultra-low phase noise to generate precise FMCW waveforms, ensuring high accuracy in velocity and distance measurement for adaptive cruise control and collision avoidance.

Key Clocking Requirements for Millimeter-Wave Radar

  • Ultra-High Frequency Stability
    Ultra-High Frequency Stability

    Achieves a full-temperature stability of better than ±20 ppm across -40°C to 125°C (with high-end options reaching ±0.5 ppm).

    Prevents detection deviations after frequency multiplication.

  • Superior Phase Noise
    Superior Phase Noise

    Delivers a phase noise of < -150 dBc/Hz @ 1 kHz offset.

    Ensures local oscillator (LO) purity at 77 GHz and enables the detection of weak targets.

  • Wide-Temperature High Reliability
    Wide-Temperature High Reliability

    Fully qualified to the AEC-Q200 standard.

    Operates reliably across a wide temperature range of -40°C to 125°C.

    Features an ultra-low aging rate of ≤±3 ppm/year.

  • Miniaturization & Low Power Consumption
    Miniaturization & Low Power Consumption

    Available in compact 3225, 2520, and 2016 SMD footprints.

    Features an OE (Output Enable) standby function with ultra-low power consumption at the μA level.
