Choosing the right RF connector begins with defining your system requirements. Two of the most important parameters are frequency range and impedance. For example, SMA connectors are widely used up to 18 GHz (and extended versions up to 26.5 GHz), while BNC connectors are typically used below 4 GHz. Impedance is equally critical as most RF systems require 50 ohm connectors, while video and broadcast systems use 75 ohm.

Beyond these, you’ll need to consider power handling, environmental requirements and mechanical constraints. For instance, a rugged outdoor wireless application may call for an environmentally sealed TNC connector, while a compact IoT device may need a board-mounted MCX. Durability, mating cycles, size and ease of assembly are also practical design considerations.
