Rogers high frequency PCB vs. FR4 PCB

Rogers High Frequency PCB and FR4 PCB are two different types of printed circuit boards (PCBs) that have some differences in high frequency signal transmission and performance.

The characteristics, applications and comparisons of these two PCBs will be introduced in detail below.

Rogers High Frequency PCB

Rogers high-frequency PCB is a circuit board with excellent high-frequency performance produced by Rogers Corporation. It has the following characteristics:

  1. Excellent high-frequency performance: Rogers high-frequency PCB has low dielectric constant (Dk) and low dielectric loss (Df), which can effectively reduce signal loss during transmission and improve signal transmission speed and stability.
  2. Excellent thermal performance: Rogers high-frequency PCB has good thermal conductivity and can effectively conduct heat away from the circuit board to avoid overheating that affects the performance of the circuit board.
  3. Corrosion resistance: Rogers high-frequency PCB has good corrosion resistance and can resist the erosion of chemical substances and extend the service life of the circuit board.

Application areas:

  1. High-frequency communication equipment: such as mobile communication base stations, satellite communication equipment, etc.
  2. Radar and electronic warfare systems: such as radar antennas, electronic warfare systems, etc.
  3. High-speed digital signal processing equipment: such as high-speed computers, digital signal processors, etc.


FR4 PCB is a common printed circuit board made of fiberglass reinforced epoxy resin. It has the following characteristics:

  1. Lower cost: FR4 PCB is a relatively economical circuit board material suitable for mass production and application.
  2. Stable dielectric properties: FR4 PCB has relatively stable dielectric properties and can meet the requirements of general electronic equipment.
  3. High mechanical strength: FR4 PCB has good mechanical strength and impact resistance, and can withstand certain external pressure and impact.

Application areas:

  1. Consumer electronics: such as mobile phones, tablets, digital cameras, etc.
  2. Industrial control equipment: such as PLC, sensors, actuators, etc.
  3. Automotive electronics: such as ECU, ABS controller, etc.

High frequency PCB and RF4 PCB comparison and selection

When choosing a PCB, you need to compare and select based on specific application scenarios and needs.

Rogers high frequency PCB vs. FR4 PCB

Below is a comparison of Rogers high frequency PCB and FR4 PCB:

  1. High-frequency performance: Rogers high-frequency PCB has excellent high-frequency performance and can meet the requirements of high-frequency signal transmission, while FR4 PCB has relatively poor performance in high-frequency signal transmission. Therefore, if you need to transmit high-frequency signals, it is recommended to choose Rogers high-frequency PCB.
  2. Cost: The cost of FR4 PCB is relatively low and suitable for mass production and application. The cost of Rogers high-frequency PCB is higher, but it has the advantages of excellent high-frequency performance and corrosion resistance. Therefore, when choosing a PCB, you need to weigh it based on the specific application scenario and budget.
  3. Mechanical strength and impact resistance: FR4 PCB has good mechanical strength and impact resistance, and can withstand certain external pressure and impact. Rogers high-frequency PCB is relatively poor in this regard. Therefore, the mechanical stress and impact tolerance of the device need to be considered when selecting a PCB.
  4. Environmental adaptability: Rogers high-frequency PCB has good corrosion resistance and weather resistance, and can work in harsh environmental conditions. FR4 PCB is relatively poor in this regard and needs to take corresponding protection measures. Therefore, the working environment and conditions of the equipment need to be considered when selecting a PCB.

In summary, Rogers high-frequency PCB and FR4 PCB each have their own advantages and disadvantages, and they need to be selected according to specific application scenarios and needs. If you need to transmit high-frequency signals and have low cost requirements, you can choose Rogers high-frequency PCB; if you need large-scale production and application and have high cost requirements, you can choose FR4 PCB.
