1.0-2.3 Adapters

Compact coaxial adapters for seamless RF transitions between 1.0-2.3 and other standard interfaces including BNC, SMA, N-Type, and HD-BNC.

Overview

Amphenol RF’s 1.0-2.3 adapters are designed to support high-density, high-performance RF applications where space savings and signal integrity are critical. These compact DIN-style adapters offer reliable in-series and between-series conversions in both 50 ohm and 75 ohm configurations, ideal for broadcast, instrumentation, and telecommunication systems.

Available in a variety of straight and bulkhead designs, these adapters feature precision-machined components and durable plated finishes to ensure consistent electrical performance up to 10 GHz. The 1.0-2.3 interface allows engineers to maximize panel space without sacrificing signal quality, and is commonly used in conjunction with BNC, SMA, and N-Type connectors across high-frequency applications.

Features and Benefits
  • In-series and between-series configurations with BNC, SMA, N-Type, and HD-BNC interfaces.

  • Available in 50 Ω and 75 Ω versions for standard and broadcast-specific needs.
  • Compact design supports dense RF layouts and front-panel installations.
  • Bulkhead and panel-mount options enable secure integration into equipment housings.
  • Rated up to 10 GHz depending on configuration and connector pairing.
