Product Description
Custom Multilayer PTFE High Frequency PCB Board For 5G Base Station RF Module
This custom multilayer PTFE high frequency PCB is engineered for 5G base station RF front-end modules, phased array antennas and microwave signal transmission. Adopting high-performance PTFE (Teflon) dielectric substrate, the circuit board features ultra-low dielectric constant (Dk) and extremely low dissipation factor (Df), effectively reducing insertion loss and signal distortion under GHz & millimeter wave frequency bands.
