Astra MT77 Material Overview

Astra MT77 is a breakthrough dielectric material designed for millimeter-wave frequencies and beyond. It delivers exceptional electrical performance that remains stable across a broad frequency range and temperatures (-40°C to +140°C), even up to W-band frequencies. As a cost-effective alternative to PTFE and other commercial microwave laminates, it meets the demands of modern commercial RF/microwave printed circuit designs while offering ultra-low loss and reliable performance.
