RO4725JXR High Frequency PCB
Shot 1: Introduction
Rogers RO4725JXR Antenna-grade PCB are composed of a hydrocarbon, ceramic, and woven glass composite. The resin system of the dielectric materials provides essential properties for optimal antenna performance. RO4725JXR laminate is fully compatible with traditional FR-4 and high-temperature lead-free solder processing. Unlike conventional PTFE-based laminates, RO4725JXR laminate does not require special treatment for plated through-hole preparation. This makes RO4725JXR PCB a cost-effective alternative to traditional PTFE-based antenna materials, enabling designers to achieve a balance between cost and performance.
Shot 2: Features
Rogers RO4725JXR laminate showcases distinctive attributes:
Low Dielectric Constant: With a precise value of 2.55 ± 0.05 at 10GHz, signal propagation is optimized. Consistent signal transmission and reception are ensured by a stable dielectric constant.
Low Z-axis CTE: Maintaining stability, the coefficient stands at 25.6 ppm/°C, preventing material expansion or contraction amidst temperature fluctuations.
Low TCDk: The +34 ppm/°C TCDk guarantees a stable dielectric constant across varying temperatures.
Low Dissipation Factor: At 10GHz, the 0.0026 dissipation factor minimizes energy loss as heat during signal transmission.
High Tg: With a Tg exceeding 280°C, the material retains its physical properties even under high-temperature conditions.
Reduced PIM Value: Notably, RO4725JXR boasts a reduced passive inter-modulation (PIM) value of -166 dBC, enhancing antenna performance, particularly in high-power scenarios.
