Looking for Ultra-Low Loss Circuit Boards? Discover RT/duroid 5880 High Frequency PCBs

June 25, 2025

Why Choose RT/duroid 5880 High Frequency PCBs?

RT/duroid 5880 laminates are PTFE-based composite materials reinforced with random glass fibers, engineered for high-frequency and broadband applications. With an ultra-low dielectric constant (Dk) and minimal signal loss, they ensure superior signal integrity in demanding RF and microwave environments.

Key Benefits of RT/duroid 5880 PCBs:

Low & Stable Dk (2.20 ± 0.02) – Ensures consistent signal propagation
Ultra-Low Dissipation Factor (0.0009 @ 10GHz) – Minimizes energy loss
Near-Zero Moisture Absorption (0.02%) – Performs reliably in humid conditions
Isotropic Signal Propagation – Uniform performance in all directions
Chemical & Solvent Resistant – Withstands harsh processing environments
Best-in-Class Electrical Loss – Lowest loss among reinforced PTFE materials

PCB Manufacturing Capabilities

1. Flexible Design Options
Double-sided, Multilayer & Hybrid PCBs
Copper Weights: 1oz (35µm) & 2oz (70µm)
Dielectric Thickness: 6mil to 127mil (customizable)
Panel Sizes: Up to 400mm × 500mm

2. Custom Finishes & Aesthetics
Solder Mask Colors: Green, Black, Blue, Yellow, Red, and more
Surface Finishes: ENIG, HASL, Immersion Silver/Tin, OSP, Bare Copper, Pure Gold, ENEPIG

Applications of RT/duroid 5880 PCBs

Ideal for high-frequency, military, and aerospace applications, including:
Commercial Airline & Broadband Antennas
5G & Millimeter-Wave Circuits
Satellite & Radar Systems
Missile Guidance & Defense Electronics
Point-to-Point Digital Radio Antennas

Why RT/duroid 5880 Stands Out?

Ultra-Low Signal Loss – Optimized for high-frequency performance
Reliable in Extreme Conditions – Resists moisture, chemicals, and thermal stress
Proven in Critical Applications – Trusted by military and telecom industries
