What Is a 5G Router PCB?
A 5G router PCB is a high-performance printed circuit board specifically designed for 5G wireless router systems. It supports high-frequency RF signals, high-speed digital data transmission, and multi-antenna architectures, which place extremely high demands on PCB materials, impedance control, and manufacturing precision.
Compared with traditional router PCBs, 5G router PCBs must handle higher frequencies, wider bandwidths, and stricter signal integrity requirements.
Key Technical Requirements of 5G Router PCB
A high-quality 5G router PCB must meet several critical requirements:
-
Low dielectric loss at high frequencies
-
Precise impedance controlled PCB design
-
Excellent signal integrity for high-speed interfaces
-
Stable dielectric constant across frequency bands
-
Good thermal management for RF and power devices
These requirements are essential for stable and reliable 5G performance.
Material Selection for 5G Router PCB
Material choice is one of the most important factors in 5G router PCB design. Commonly used materials include:
