High Frequency PCB
For modern RF, microwave, and high-speed digital applications, standard PCB materials often fall short. High Frequency PCBs are engineered to maintain signal integrity at higher transmission rates, typically operating in the 500MHz to 2GHz range and beyond.
However, achieving consistent performance at these frequencies requires more than just standard fabrication. It demands precise material selection, strict impedance control, and a manufacturing partner with deep RF expertise.
Critical Material Selection for Signal Integrity
The core of any high-frequency board is its dielectric material. Unlike standard FR-4, the Dielectric Constant (Dk or Er) of these specialized materials must remain stable across the operating frequency. Any variation directly impacts impedance, leading to signal loss or reflection.

Leading designers turn to proven materials like Rogers laminates for their predictable electrical performance. Our most commonly specified materials include:
| Material | Dielectric Constant (Dk) | Key Advantage |
|---|---|---|
| RO4350B | 3.48 ±0.05 @ 10 GHz | Cost-effective, ideal for automotive & microwave |
| RO4003C | 3.38 ±0.05 @ 10 GHz | Low loss, compatible with FR-4 processing |
| RO3003 | 3.00 ±0.04 @ 10 GHz | Very low loss for millimeter wave applications |
| RT5880 | 2.20 ±0.02 @ 10 GHz | Lowest loss, PTFE-based for maximum performance |
| RO3010 | 10.2 ±0.30 @ 10 GHz | High Dk for circuit size reduction |
Precise Impedance Control & Manufacturing Tolerances
Specifying the right material is only half the challenge. Achieving your target impedance (typically ±10%) requires rigorous process control over:
Conductor width and spacing: Maintained to ±3mil/3mil tolerances.
Substrate thickness: Controlled across the entire panel.
Copper weight: Options from 0.5oz to 2.0oz finished.
Stack-up design: Expert assistance for multi-layer RF structures.
