RF Connector Types

 

Choosing the right RF connector isn’t just about fit—it directly affects signal quality, frequency performance, and reliability. This chart organizes connectors by size and frequency range, making selection easier.
At the smallest end, ultra-miniature and microminiature types like MMCX, MCX, and SMP are used in compact devices such as mobile antennas, routers, and high-density systems. They support up to around 6–40 GHz depending on the type, but are mainly chosen for space-saving designs.
Miniature and subminiature connectors like SMA and SMB are extremely common. SMA, for example, goes up to about 26.5 GHz and is widely used in RF testing, communication systems, and lab setups due to its balance of size and performance.
Moving to medium connectors, BNC and TNC are easier to handle and commonly used in test equipment, video signals, and rugged environments. Their frequency range is lower, but they offer strong mechanical connections.
At the larger end, connectors like Type N and DIN 7/16 are built for high power and outdoor telecom applications such as base stations. They handle lower frequencies but provide excellent durability and low signal loss.
In short, smaller connectors = higher frequency and compact use, while larger connectors = higher power and rugged applications.
