Inside the Microwave Connector: Materials and Construction

At first glance, the construction of RF/microwave connectors seems quite straightforward. Physical dimensions are dictated largely by the desired combination of RF characteristics—characteristic impedance, power handling (current capacity and voltage breakdown), and compatibility with typical cables. The choice of body metal, plating, and dielectric material will depend on environmental requirements—water, corrosion, temperature, air pressure (altitude), mating-unmating cycles, shock and vibration. Of course, construction must be compatible with interface standards for the mating methods: threaded, bayonet, friction fit, etc.
