What is High Frequency PCB? – Engineered for Signal Purity at Scale
Standard PCBs falter above 1GHz due to three critical issues:
- Dielectric Loss: Traditional FR-4 loses 1.2dB/in, equivalent to a 30% signal energy drain
- Impedance Discontinuity: Right-angle traces cause 50% signal reflection, distorting high-frequency signals
- EMI Noise: Uncontrolled trace routing increases crosstalk by 40% in dense layouts
Our High Frequency PCBs address these with:
- Advanced Materials: Rogers 4350B substrates (0.3dB/in loss at 1GHz) for 60% lower signal decay
- Structural Precision: Microstrip designs with 45° angles + blind vias, reducing reflection by 40%
5G Smartphone Breakthrough: A leading brand achieved 25% better signal sensitivity and 15% longer 5G battery life using our Roger-based PCBs, driving 1 million+ unit sales and ongoing collaboration.
Three Technical Advantages That Define High Frequency PCB
| Performance Metric | Standard PCB | ThinDry High Frequency PCB | Operational Impact |
|---|---|---|---|
| 1GHz Signal Loss | >1dB/in | 0.45dB/in (Rogers 4350B) | Enables 2x longer signal transmission distances |
| Impedance Control | ±10% tolerance | ±5% tolerance | Supports PCIe 5.0 and HDMI 2.1 protocols |
| Thermal Stability | ≤125℃ | ≤180℃ (氰酸酯基板) | Reliable in automotive engine bays (150℃ sustained) |
Electric Vehicle Case: An NEV motor controller using our 180℃-rated cyanate ester PCBs achieved 3% signal attenuation at 150℃, passing ISO 26262 certification and enabling 300,000+ vehicle deployments.
Design Best Practices for High-Frequency Performance
① Trace Routing: The “3S” Principle
- Short: Limit trace length to <10cm; every 5cm adds 15% loss (e.g., 20cm trace = 30% additional loss)
- Straight: 45° angles reduce reflection coefficient from 0.5 to 0.3 (40% improvement)
- Simple: ≤3 vias per signal path; buried vias cut via loss by 30% compared to through-hole
Satellite Payload Optimization: Reducing via count by 40% and adopting buried vias lowered a low-orbit satellite’s bit error rate from 0.1% to 0.001%, meeting space-grade reliability standards.
② Layer Stackup Strategy
- Dielectric Selection: Use low-Dk materials (Dk <3.5) for 20% lower propagation delay
- Ground Plane Design: Full ground plane coverage reduces EMI radiation by 50%
Radar System Case: A military radar’s signal-to-noise ratio improved 30% with our 4-layer stackup featuring Rogers 4350B and solid ground planes.
High Frequency vs. High-Speed PCBs: Key Distinctions
| Characteristic | High-Speed PCB (e.g., Server Boards) | High-Frequency PCB (e.g., Radar Modules) |
|---|---|---|
| Core Challenge | Signal edge rate (<1ns rise time) | Frequency stability (>1GHz operation) |
| Critical Material | High TG FR-4 for thermal stability | Low Df ceramics/PTFE for dielectric loss |
| Design Focus | Topology optimization | Impedance continuity and material selection |
| Typical Loss | 0.8dB/in at 1GHz (FR-4) | 0.3dB/in at 1GHz (Rogers 4350B) |
