Overview

CAES provides adapters for test labs and systems used in high-performance commercial, military and space applications. Delivering superior electrical performance, these durable, precision coaxial test adapters function as connector-savers to protect expensive test equipment and panel connectors from damage and wear.

Constructed of gold-plated beryllium copper and stainless steel, our 50-ohm adapters operate from DC to 18 GHz. Interfaces conform to MIL-PRF-39012 and MIL-STD-348.

CAES also supplies an extensive array of between-series system coaxial adapters for test equipment and high-power systems. We carry most commonly used connector types. All of our adapters are designed to mil-standard interfaces and many meet stringent MIL-T-81490 requirements.

Our most common test adapters are summarized below. Contact CAES for part numbers for TR, SC, and other less common interfaces.
