Next-Gen Laminates for Automotive Radar Sensors

Rogers Corporation has announced the RO3003G2, the latest addition to its RO3000 Series of PTFE high-frequency laminates. The RO3003G2 laminates are built on their industry leading RO3003 platform to provide radar sensor designers with improved insertion loss and reduced dielectric constant (Dk) variation.

The combination of Roger's optimized resin and filler content along with the introduction of Very Low Profile ED copper translates to Dk of 3.00 @ 10 GHz (clamped stripline method) & 3.07 @ 77 GHz (microstrip differential phase length method). RO3003G2 laminates also show very low insertion loss of 1.3dB/inch for 5 mil laminates as measured by the microstrip differential phase length method.

RO3003G2 laminates are an extension of RO3003 laminates that incorporate Rogers’ decades-long experience working with its automotive radar customers and understanding the increasing product performance requirements.

Key Features of the RO3003G2 laminates:

  • Reduce insertion loss via a new Very Low Profile Electrodeposited Copper (VLP ED).
  • Reduce dielectric constant variation through PCB processing as a result of a homogeneous construction and incorporating VLP ED foil.
  • Enable designs with denser/smaller diameter micro vias, achieved by an advanced filler system using small rounded particles.
  • Rogers RO3003G2 high-frequency PTFE laminates are available in standard panel sizes of 24 x 18 in. (610 x 457 mm), and 24 x 21 in. (610 x 533.75 mm) with 0.5 oz. (18 µm) or 1.0 oz. (35 µm) ED Cu foil and Rolled Cu foil.
  • Available in dielectric thicknesses of 0.005 and 0.010 inch.
