# What should be assumed regarding the upper frequency of sma connectors

There are infinitely many sellers of sma connectors of various kind in ebay or other stores. This one is an example. But they very seldom specify what is the maximum frequency at which the device can be used. Is there something generally assumed here? perhaps some rule of thumb (in particular if it is said that the connector is made of brass and gold plated)?
