Product details
Samtec Inc.'s QMS-078-01-H-D-EM2-PC4 represents a quantum leap in Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board) for millimeter-wave applications. This 60GHz+ rated connector solution enables next-generation radar systems and 5G mmWave infrastructure with unmatched signal integrity.The Header, Outer Shroud Contacts configuration features precision-machined contacts for waveguide transitions. The design maintains VSWR <1.2:1 up to 70GHz, outperforming conventional RF connectors.Available in 164 (156 + 8 Power) configurations, the connector supports phased array antenna elements. The optimized layout minimizes phase variation across channels.The /4 0.025" (0.64mm) spacing has been calculated for 60GHz operation. This precision spacing prevents unwanted coupling between adjacent antenna feeds.The 2 row architecture provides optimal ground return paths for millimeter-wave signals. This configuration has been validated for 64-element beamforming arrays.Engineered for Board Edge, Straddle Mount installation, the connector features kinematic mounting for precise alignment. The design compensates for PCB thermal expansion in outdoor deployments.Critical Ground Bus (Plane), Power Pins (8) include integrated radomes and hermetic sealing. These protections ensure reliable operation in all weather conditions.The Gold formulation minimizes skin effect losses at millimeter-wave frequencies. Special surface treatments maintain consistent performance up to 100GHz.With 30.0µin (0.76µm) precision, the contacts achieve optimal RF performance. This control is essential for maintaining signal integrity in radar applications.
