Rogers DiClad 880 High Frequency PCB - Ultra-Low Loss PTFE Material for RF Applications

August 9,2025

Introduction

Rogers DiClad 880 is a PTFE-based laminate with woven fiberglass reinforcement, engineered for ultra-low loss, high-frequency applications. Its optimized composition delivers:
Lower Dk & Df than standard PTFE laminates
Superior Dk uniformity for precision RF components
Enhanced dimensional stability for critical designs
