RO4000 LoPro laminates use a proprietary Rogers’ technology that allows reverse treated foil to bond to standard RO4000 dielectric. This results in a laminate with low conductor loss for improved insertion loss and signal integrity while maintaining the other desirable attributes of the standard RO4000 laminate system. RO4000 hydrocarbon ceramic laminates are designed to offer superior high frequency performance and low cost circuit fabrication. The result is a low loss material which can be fabricated using standard epoxy/glass (FR-4) processes and do not require specialized via preparation such as sodium etch for lower manufacturing cost.


  • Low insertion loss versions of RO4003C™, RO4350B™ and RO4835™ laminates
  • Multi-layer board (MLB) capability
  • CAF resistant


  • Lower insertion loss allows for higher operating frequency designs (even greater than 40 GHz)
  • Reduced passive inter-modulation (PIM) for base station antennas
  • Improved thermal performance due to lower conductor loss
