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.

Common Materials for High Frequency PCB

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 JLCPCB offers include:

Rogers

Rogers Material:

RO4350B (Dk=3.48, Df=0.0037)

Rogers-RO4350B:

This material is a strengthened glass hydrocarbon/ceramic material with a dielectric constant of 3.48 at 10GHz, which makes it commonly used in high-frequency power amplifier designs. The RO4350B laminate has a low Z-axis coefficient of thermal expansion (CTE), which ensures high stability of multilayer circuits interconnected by plated through holes (PTH).

PTFE Teflon

PTFE Teflon Material:

ZYF255DA (Dk=2.55, Df=0.0018)

ZYF265D (Dk=2.65, Df=0.0019)

ZYF300CA-C (Dk=2.94, Df=0.0016)

ZYF300CA-P (Dk=3.0, Df=0.0018)

PTFE Teflon PCB has outstanding comprehensive performance in practical use and is an ideal material choice for high-complexity and high-reliability designs. It has good temperature resistance, strong heat dissipation, excellent dielectric properties, and good mechanical stability. It is very durable in use and can withstand a certain amount of oxidation and UV rays, so it is also a cost-effective option.

The Benefits of JLCPCB 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

Trace width, spacing, and dielectric properties are used to tune the impedance. Impedance matching should be there for better signal transmission. That's why in RF transmission lines 50Ω, 75Ω, and 100Ω are used.

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.
