5G PCB Design: High-Frequency Material Selection(Rogers, PTFE, LCP)

Leave a Comment / Blog / By

1. Introduction The success development of 5G PCB designs hinges critically on material selection. As 5G technology pushes frequencies into the millimeter-wave (mmWave) range of 24-77 GHz and beyond, traditional printed circuit board materials like standard FR-4 struggle to maintain signal integrity due to high dielectric loss and unreliable electrical properties. The selection of substrate […]
