IS680 laminate materials exhibit exceptional electrical properties which are very stable over a broad frequency and temperature range.
IS680 is suitable for many of today’s commercial RF/ microwave printed circuit designs. It features a dielectric constant (Dk) that is stable between -55°C and +125°C up to W-band frequencies. In addition, IS680 offers a very low dissipation factor (Df), making it an extremely cost-effective alternative to PTFE and other commercial microwave laminate materials in double sided applications.
