DESIGN FEATURES & SPECIFICATIONS |
| DESIGN FEATURES:
SGMC Microwave's 1.85mm series are precision grade connectors
designed for use with microwave applications requiring
excellent performance up to 65 GHz. Optimum results are
achieved with the use of a 1.85mm outer conductor diameter and
air dielectric. The 1.85mm series is mechanically
compatible with 2.4mm connector series. The 1.85mm
interface is designed to insure the outer conductors of mating
connectors engage and align before the center contacts engage
preventing damage to the female center contact tines.
Connector designs for SGMC Microwave's 1.85mm series are provided for
semi-rigid cable assemblies, receptacles and precision
adaptors. |
