• Stock number 878-2371 is a 50 Ohm SMA receptacle to BNC plug RF coax adapter

• Stock number 878-2378 is a 50 Ohm SMA plug to BNC receptacle RF coax adapter

Features and Benefits

• SMA-BNC RF Connector

• Gold contact plating for excellent signal connectivity

• Robust nickel-plated brass body

Applications

The SMA, or Subminiature A connector, are used in radio frequency applications up to 18 GHz, and are typically found in wi-fi systems. The BNC connector is typically used in lower frequency and power applications and is commonly used in analogue signal applications such as pre-digital television broadcasts and laboratory test equipment. This inter-series adapter allows interfacing between both types of connector and is often used in laboratory conditions or for testing and evaluating products.
