What is a High Frequency PCB?

As the frequency increases beyond a certain limit, signal losses in standard FR4 boards rise significantly. To address this, we offer a range of High-Frequency PCBs, designed specifically for MHz to GHz applications. These boards use low-loss dielectric materials with a reduced loss tangent, minimizing signal degradation. This ensures controlled electromagnetic interference (EMI) and reliable, high-speed signal transmission.

High Frequency PCB Materials

Unlike standard FR4 boards, High-Frequency PCBs can be selected based on Dk (dielectric constant) and Df (dissipation factor). The lower these values, the better the signal integrity at high frequencies. Some materials EBEEPCB offers include Rogers and PTFE Teflon.

Rogers RO4350B is a strengthened glass hydrocarbon/ceramic material with a dielectric constant of 3.48 at 10GHz. It has a low Z-axis coefficient of thermal expansion (CTE), ensuring high stability of multilayer circuits interconnected by plated through holes (PTH).

Structure and Properties of High Frequency PCB

High frequency PCBs use specialized materials with low dielectric constant and low dissipation factor to minimize signal loss at high frequencies.

1. Rogers RO4350B: — A strengthened glass hydrocarbon/ceramic material with a dielectric constant of 3.48 at 10GHz, commonly used in high-frequency power amplifier designs.
2. PTFE Teflon: — PTFE Teflon PCB has outstanding comprehensive performance in practical use and is an ideal material choice for high-complexity and high-reliability designs.
3. Copper Foil: — A good copper foil with a smooth surface and low resistance ensures lower losses at microwave frequencies.

Benefits of High Frequency PCB

Low Dielectric Loss

Lower loss in PCB dielectric means higher signal strength. Dielectric losses can cause EMI failure and excessive crosstalk. With a low dissipation factor (Df), signal losses can be controlled at high frequencies.

Stable Performance at High Speeds

At high speed, signals travel in dielectric space, and copper traces act as waveguides. Substrate having lower loss tangent (Df) ensures better signal performance throughout.

Excellent Signal Integrity

Factors like impedance mismatch and signal delays increase if the substrate has higher parasitic components. With high-frequency substrates, delays can be controlled in RF and high-speed circuits.

High Frequency PCB Design Considerations

Common Applications of High Frequency PCBs

RF and microwave systems operate in the 3 kHz to 300 GHz range, and high-frequency applications often require specialized materials. Materials like Rogers are therefore used to design RF front-end modules that demand high accuracy and minimal signal distortion.
