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.

Key Features of Astra MT77

Property	Specification
Dielectric Constant (Dk)	3.0 (2GHz/23°C; 10GHz/23°C)
Dissipation Factor (Df)	0.0017 (2GHz; 10GHz)
Peel Strength (1oz Copper)	5.7 lb/inch
Moisture Absorption	0.1%
Coefficient of Thermal Expansion (CTE)	X-axis: 12 ppm/°C; Y-axis: 12 ppm/°C; Z-axis: 250-350 ppm/°C
Glass Transition Temperature (Tg)	200°C (DSC method)
Flammability Rating	UL 94-V0
Process Compatibility	Lead-free compatible

Processing Advantages

Astra MT77 simplifies manufacturing with multiple practical benefits:

Compatible with standard FR-4 processing workflows (no special equipment needed)
Short lamination cycles for improved production efficiency
Reduced drill wear to lower manufacturing costs
No plasma desmear required, streamlining processing steps
Good flow and fill characteristics for reliable layer adhesion
Strong dimensional stability across production and operating conditions
Supports multiple lamination cycles for flexible manufacturing
Compatible with any layer technology, HDI, and VIPPO designs

Typical Applications

This 2-layer Astra MT77 PCB is specifically tailored for automotive RF/microwave systems, including:

Long-range antennas and radar for adaptive cruise control
Pre-crash detection systems
Blind spot monitoring
Lane departure warning systems
Stop-and-go systems
