In RF, microwave, and high-speed electronic systems, signal loss directly affects performance, efficiency, and reliability. Choosing a professional low loss high frequency PCB supplier is critical for ensuring stable signal transmission, accurate impedance control, and consistent manufacturing quality.
A qualified low loss high frequency PCB supplier delivers not only advanced materials, but also RF-focused engineering support and reliable production capability from prototype to volume manufacturing.
What Is a Low Loss High Frequency PCB?

A low loss high frequency PCB is designed using specialized laminate materials with low dielectric constant (Dk) variation and extremely low dissipation factor (Df). These characteristics significantly reduce signal attenuation at high frequencies.
Compared with standard FR-4, low loss high frequency PCBs provide:
-
Lower insertion loss
-
Improved signal integrity
-
Better phase stability
-
More accurate impedance control
Materials Supported by a Low Loss High Frequency PCB Supplier
A professional low loss high frequency PCB supplier offers a wide range of RF and microwave materials, including:
-
Rogers RO4003, RO4350, RO3003 series
-
Taconic RF-35, TLY, and CER series
-
PTFE-based laminates (Duroid 5880, 5870)
-
Hybrid stackups combining RF materials with FR-4
Material selection is optimized based on frequency, cost, and application requirements.
