Rogers Substrate Applications in RF & Microwave PCBs

Rogers high-frequency laminates are widely used in RF, microwave, and high-speed PCB applications where stable dielectric properties, low loss, and reliable performance are critical.
At Top RF PCB, we specialize in manufacturing RF PCBs using the most commonly specified Rogers substrates, supporting both prototype and mass production with fast lead times.

Why Rogers Substrates Are Used in RF PCBs

Compared with standard FR-4, Rogers materials provide:

• Stable dielectric constant (Dk) across frequency and temperature

• Ultra-low dielectric loss (Df) for high-frequency signals

• Excellent impedance control and signal integrity

• Superior thermal and dimensional stability

• Proven reliability for aerospace, telecom, and military applications

These advantages make Rogers substrates the first choice for RF, microwave, and millimeter-wave PCB designs.
