Astra® MT77 PCB Fabrication

astra®-mt77-pcb-fabrication

Astra® MT77 PCB Fabrication. Astra® MT77 materials are a breakthrough, very low-loss dielectric constant (DK) product for millimeter wave frequencies and beyond.

Astra MT77 laminate materials exhibit exceptional electrical properties which are very stable over a broad frequency and temperature range. Astra MT77 is suitable for many of today’s commercial RF/microwave printed circuit designs. It features a dielectric constant (DK) that is stable between -40°C and +140°C at up to W-band frequencies. 加えて, Astra MT77 offers an ultra-low dissipation factor (Df) の 0.0017, making it a cost-effective alternative to PTFE and other commercial microwave laminate materials.

Key applications include long antennas and radar applications for automobiles, such as adaptive cruise control, pre-crash, blind spot detection, lane departure warning and stop and go systems.
