Coaxial Connector Descriptions & Drawings
An RF connector is an electrical connector designed to work at radio frequencies in the multi-megahertz range. RF connectors are typically used with coaxial cables and are designed to maintain the shielding that the coaxial design offers. Better models also minimize the change in transmission line impedance at the connection. Mechanically they provide a fastening mechanism (thread, bayonet, braces, push pull) and springs for a low ohmic electric contact while sparing the gold surface thus allowing above 1000 reconnects and reducing the insertion force. Research activity in the area of radio-frequency (RF) circuit design has surged in the last decade in direct response to the enormous market demand for inexpensive, high data rate wireless transceivers. - Wikipedia

| Type | Male | Female |
| 2.4 mm Maximum Frequency: 50 GHz This family is not directly mateable with the SMA family. Quality grades; general purpose, instrument, and metrology. |  |  |
| 7/16 DIN Maximum Frequency: 7.5 GHz Cellular and other "wireless" applications, especially on towers. Rated to 7.5 GHz. Low PIMs. | ||
| APC-2.4 (Amphenol Precision Connector, 2.4 mm) | ||
| APC-3.5 (Amphenol Precision Connector, 3.5 mm) | ||
| APC-7 (Amphenol Precision Connector, 7 mm) Maximum Frequency: 18 GHz Offers the lowest reflection coefficient and most repeatable measurement of all 18 GHz connectors. Hermaphrodite design. Preferred connector for metrology and calibration. | ||
| BNC (Bayonet Navy Connector) (Amphenol claims it's for Bayonet Neill Concelman) Maximum Frequency: 2 GHz OSBDesigned for military use. Wide acceptance in video and RF applications to 2 GHz. |  |  |
| C Maximum Frequency: 12 GHz Medium-size, 50 Ω impedance. Type N connectors, but are bayonet locking. | ||
| F Maximum Frequency: 1 GHz Utilized in television cable and antenna applications. 75 Ω characteristic impedance. 3/8-32 coupling thread. | ||
| GR874 Maximum Frequency: 8.5 GHz Hermaphroditic, 50 Ω impedance with a slide-on interface. | ||
| GR900BT Maximum Frequency: 8.5 GHz Hermaphrodite connectors. Used in highly critical laboratory applications at frequencies up to 8.5 GHz. | ||
| N (Navy) OSN Maximum Frequency: 12 GHz Uses an internal gasket to seal out the environment. |  |  |
| RCA Maximum Frequency: 10 MHz Round, press-on connector used for consumer-grade audio and composite video connections. Color coded as follows: red (audio-Right), black or white (audio-Left) and yellow (composite video). | ||
| SMA (Sub-Miniature A) OSM/3mm Maximum Frequency: 12 GHz One of the most commonly used RF/microwave connectors. Standard SMA connectors are designed for interconnects to 12.4 GHz. A good SMA is useable to 18 GHz. | | |
| SMB (Sub-Miniature B) OSMB |  |  |
| SMC (Sub-Miniature C) OSMC |  |  |
| SSMA (Sub-SMA) OSSM | ||
| TNC (Threaded Navy Connector) Maximum Frequency: 2 GHz OSTThreaded version of the BNC connector. Both 50 Ω and 75 Ω versions are available. |  |  |
| UHF Maximum Frequency: 300 MHz Non-constant (characteristic) impedance, suitable for use up to 300 MHz but can be rated for up to 500 MHz. |  |  |
