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. In addition, Astra MT77 offers an ultra-low dissipation factor (Df) of 0.0017, making it a cost-effective alternative to PTFE and other commercial microwave laminate materials.

  1. Hi,
    I need a substrate Astra® MT77 material with thickness of 0.024″ (24mil) and DK= 3.0. Can you provide that?
    Thank you,

    • Good morning my friend.

      Yes. we have this types Astra® MT77 material substrate. do you only need the blank substrate. or you need a PCB Boards.
      if you need the PCB boards. please send me the PCB gerber files.

      thank you.
