Engineered for 76–77 GHz
Radar Performance.
Built for ADAS Reliability.
Advanced driver assistance systems and automotive radar platforms require precise RF control to ensure safe and accurate operation. As modules shrink and antennas sit closer together, unwanted reflections and interference can degrade radar performance—and the safety systems that depend on it.

Optimized Absorber Solutions for Automotive Radar & ADAS
Built for the Module.
Tuned for the Safety Mission.
MAST Technologies provides RF absorber materials designed to support reliable high-frequency performance within compact radar assemblies—engineered specifically for the 76–77 GHz automotive radar band and the proximity-constrained modules ADAS platforms rely on.
These materials help reduce unwanted reflections, manage RF energy inside radar modules, and maintain consistent performance as automotive electronics continue to shrink in size.
MAST provides absorber materials optimized to manage resonance, emissions, and near-field coupling across a wide frequency range and at multiple integration levels — from chip-level mitigation to enclosure-scale damping.

Three Engineered Approaches.
One Goal: Better Radar Performance.
MR21 Series
Targeted Attenuation at 76–77 GHz.
Tuned Frequency Absorbers optimized for the 76–77 GHz automotive radar band—engineered to deliver narrowband attenuation at the specific frequencies modern ADAS modules operate at, without introducing unnecessary broadband loss across the rest of the system.
Band 76–77 GHz (Automotive Radar)
MR21 Series
Q-Factor Damping for Compact Radar Enclosures.
Cavity Resonance Absorbers engineered for the compact electronic enclosures that automotive radar modules are built into. Suppresses resonant peaks inside metallic cavities, lowers Q-factor, and protects radar performance from cavity-induced field amplification.
Use Compact Radar Module Enclosures
MR21 Series
Broadband Absorption for Larger Radar Enclosures
Broadband lossy foam absorbers for attenuation within radar module enclosures where geometry allows for foam placement. A cost-effective wideband solution for managing RF energy inside enclosures that have the volume to accommodate foam-format absorbers.
Format Foam · Cavity Placement
The combined effect: reduced unwanted reflections, managed RF energy inside radar modules, and consistent performance as automotive electronics continue to shrink in size — supporting the side-lobe reduction, cross-talk mitigation, and stable module performance ADAS safety systems depend on.
