RF adapters are devices that allow two different types of RF (radio frequency) connectors to be connected together, allowing a signal to pass through from one type of cable to the other. Generally these adapters change between different types of "series" of cables, such as an N-Series to an SMA-Series or a SMA-Series to a BNC-Series. They provide a cost-effective and convenient way for equipment with different connector sizes to communicate. However, there are certain considerations that need to be taken into account in terms of signal quality, power compatibility, and impedance when connecting different series together.
