RF COAX series

Microminiature Coax Connectors

Our microminiature coax connectors offer a versatile solution for high density packaging.

Our space-saving microminiature coax connectors are designed for high-performance microwave systems. Built to accept multiple ohm mini coax cables, our connectors are ideally suited for applications requiring high density, reliabilty, and reduced size and weight. Our selection includes some of the aerospace and defense industry's smallest and most reliable designs. To meet your design specifications, we can accommodate harness assemblies and custom configurations.
