For amateur radio operators rf connectors are indispensable to interconnect radio equipment, antennas, measuring equipment and related components. Below is a table with the common RF connector types with additional information.
| Type | Frequency range from DC to... | Mechanical compatibility | Remarks |
|---|---|---|---|
| UHF | Mid VHF | - | Commonly known as SO-239 (Socket) and PL-259 (Plug). The name (UHF connector) comes from an era when UHF referred to frequencies above the HF (30 MHz) band. |
| BNC | 3 GHz | - | Mixing of 50Ω and 75Ω connectors is possible and should not damage the connectors. |
| DIN 7/16 | 8 GHz | - | Used in high power connections. |
| N | 18 GHz | - | Take care not to mix 50Ω and 75Ω connectors. Connecting the two variants together will damage the connectors. |
| SMA | 18 GHz | PC 3.5 & 2.92 mm | Cheaper alternative to PC 3.5 connector. |
| PC 3.5 | 34 GHz | SMA & 2.92 mm | |
| 2.92 mm | 40 GHz | SMA & PC 3.5 | Also known as K connector |
