Rogers High Frequency PCB

Rogers RF PCB refers to circuit boards fabricated with Rogers Corporation's proprietary substrates, engineered for RF/ microwave/ mmWave applications (0.5-110 GHz). Their core value lies in:
1. Ultra-low Signal Loss, Dissipation factor (tanδ) as low as 0.001 @10GHz
2. Stable EM Parameters, Dk temperature coefficient ≤ -50 ppm/℃
3. Precision Impedance Control, Transmission line tolerance ±0.75%

Product Characteristics

1. Ultra-low Dielectric Loss
Dissipation factor (tanδ) 0.0009~0.0037** (@10GHz), 40% lower than standard PTFE
Cases: RO3003™: 0.0013 @10GHz, RO4835™: 0.0037 @77GHz

2. Stable Dielectric Constant (Dk)
Temp. coefficient ≤ -50 ppm/℃ (-55℃~150℃), e.g. RO4350B™ ΔDk<±0.02 @40GHz
Frequency stability: ΔDk<±0.02 from 1-100GHz (RO3000™)

3. Low-profile Copper Foil
HVLP copper roughness Ra=0.3μm (vs. 2μm for standard foil)
77GHz benefit: 35% reduction in skin effect loss

4. CTE-matched to Copper
Z-axis CTE 17~25 ppm/℃ (matches copper's 18ppm/℃), prevents delamination
Contrast: FR-4 Z-CTE ≈70ppm/℃

5. Isotropic Substrate
XY/Z-axis Dk uniformity ΔDk<0.05, enables <0.8° phase error in phased arrays

6. Enhanced Thermal Conductivity
Special series >0.6 W/(m·K) (e.g. RO4730G3™), handles 30W/mm² power density

7. Extreme Environment Survival
Certified for space applications (1000 thermal cycles, UV radiation)
