At IMS2019,  Isola will be showcasing its Very Low Loss FR-4 Process Compatible Laminate for mmWave frequencies. Isola’s Astra MT77 laminate materials exhibit exceptional electrical properties which are very stable over a broad frequency and temperature range. It 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.

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.
