What Is a Duroid 5880 PCB?

A Duroid 5880 PCB is a high frequency printed circuit board manufactured using Rogers RT/duroid 5880 laminate, a PTFE-based material known for its ultra-low dielectric constant and extremely low dissipation factor.
Duroid 5880 PCB is widely used in:
-
Radar systems
-
Satellite communication modules
-
mmWave applications
-
Aerospace RF systems
-
High frequency antennas
Because high frequency signals are highly sensitive to material loss, Duroid 5880 PCB ensures minimal insertion loss and excellent signal integrity even at microwave and millimeter-wave frequencies.
