RO4835 Laminate by Rogers Corporation

Courtesy of Rogers Corporation

The RO4835 laminates from Rogers Corporation are high frequency circuit materials that operate up to 40 GHz. They provide 10x more resistance to oxidation than standard RF thermoset materials. The dielectric constant of RO4835 is 3.48 with a dissipation factor of  0.0037 (measured at 10 GHz). These laminates utilize RoHS compliant flame-retardant technology for applications requiring UL 94V-0 certification and also conform to the requirements of IPC-4103. The laminates are ideal for power amplifiers, phased-array radar, automotive radar and sensor applications.

RO4835 laminates, are available with Rogers proprietary LoPro reverse treat copper foil. These materials are ideal for applications requiring low insertion loss characteristics. LoPro foil provides reduced electrical variability due to its smoother copper surface, maintaining consistent performance for reliable broadband signal delivery from Digital through RF and microwave frequencies.
