Automotive FMCW-LiDAR Packages for High Reliability, Hermetic, and Complex Integration Applications

What is FMCW Technology?

FMCW (Frequency Modulated Continuous Wave) technology is a frequency continuous modulation method that uses coherent waveguides to detect the distance and speed of an object. By integrating each function using silicon photonics technology, device miniaturization is possible.

Benefits of FMCW-LiDAR

  1. High accuracy, long-range, high-resolution detection
  2. Low mutual interference with other devices
  3. Can be integrated using silicon photonics technology

Problems with FMCW-LiDAR

  1. Structure becomes more complex
  2. Tend to be larger in size
  3. Hermetic sealing is required

Kyocera develops ceramic packaging solutions
to solve the most difficult problemsof automotive FMCW-LiDAR.

Kyocera’s packages havehigh heat dissipation characteristics, are hermetic seal compliant, and help achieve miniaturization and weight reduction.

We custom design our packaging solutions for specific needs and applications to support our customers developing the next-generation of automotive technology.
