High-Frequency PCB Expertise
Rogers and PTFE Teflon PCBs for RF, microwave, 5G, and high-speed applications. Precision impedance control and low-loss materials.
What is a High Frequency PCB?
A High Frequency PCB is built with specialized low-loss dielectric materials designed for applications operating from MHz to GHz frequencies. Unlike standard FR-4, these materials maintain stable electrical properties at high speeds, ensuring minimal signal loss and excellent impedance control.
Rogers Series
RO4000/RO3000/RT/duroid, Dk 2.2–10.7
Full range of Rogers high-frequency laminates including RO4350B, RO4003C, RO3003, RT/duroid series. Ceramic-filled hydrocarbon and PTFE composites offering exceptional electrical stability for RF, microwave and mmWave applications up to 77+ GHz.
PTFE (Teflon)
Dk = 2.1–3.0, Df = 0.001–0.002
Ultra-low-loss PTFE-based materials for the most demanding high-frequency applications. Exceptional signal integrity at microwave and millimeter-wave frequencies with minimal dielectric absorption.
Panasonic / Nelco / Isola
Megtron 6/7, I-Speed, FR408HR
High-speed, low-loss laminates from leading suppliers for high-speed digital and RF hybrid applications. Mid-loss, low-loss, very-low-loss, and ultra-low-loss grades available.
Taconic / Other HF Materials
Hydrocarbon, PTFE composites
Taconic TSM/TLY series and other specialized high-frequency materials including PI, MPI, and LCP for flexible RF applications.
Key Benefits
Low Dielectric Loss
Minimized signal attenuation ensures maximum power transfer and efficiency in RF and high-speed digital circuits.
Stable Performance at High Speeds
Consistent dielectric constant across frequency and temperature ranges maintains impedance control and signal fidelity.
Excellent Signal Integrity
Low dissipation factor and tight Dk tolerance reduce reflections and crosstalk, critical for GHz-range applications.
Applications
High-frequency PCBs enable next-generation wireless and RF technology.
RF & Microwave Systems
Amplifiers, filters, antennas, and transceivers operating at microwave frequencies with stringent loss requirements.
5G Infrastructure
Base stations, beamforming antennas, and millimeter-wave modules that demand low-loss, high-frequency substrates.
Satellite Communication
Space-grade RF circuits, phased array antennas, and transponders requiring reliable performance in extreme environments.
