| Connector type | Frequency Limit | Dielectric | Comments and history |
|---|
| BNC |
4 GHz |
PTFE |
"Bayonet type-N connector", or "Bayonet Neill-Concelman" according to Johnson Components. Developed in the early 1950s at Bell Labs. Could also stand for "baby N connector". |
| SMB |
4 GHz |
PTFE |
"Sub-miniature type B", a snap-on subminiature connector, available in 50 and 75 ohms. |
| OSMT |
6 GHz |
PTFE |
A surface mount connector |
| OSX, MCX, PCX |
6 GHz |
PTFE |
MCX was the original name of the Snap-On"micro-coax" connector species. Available in 50 and 75 ohms. |
| MMCX |
|
PTFE |
Micro-miniature coax connector, popular in the wire industry because its small size and cheap price. |
| SMC |
10 GHz |
PTFE |
Sub-miniature type C, a threaded subminiature connector, not widely used. |
| SMA |
25 GHz |
PTFE |
Sub-miniature type A developed in the 1960s, perhaps the most widely-used microwave connector system in the universe. |
| TNC |
15 GHz |
PTFE |
"Threaded Neill-Concelman" connector, according to Johnson Components, it is actually a threaded BNC connector, to reduce vibration problems. Carl Concelman was an engineer at Amphenol. |
| N |
11 GHz
normal
18 GHz
precision
|
PTFE |
Named for Paul Neill of Bell Labs in the 1940s, available in 50 and
75 ohms. Cheap and rugged, it is still widely in use. Originally was
usable up to one GHz, but over the years this species has been extended
to 18 GHz, including work by Julius Botka at Hewlett Packard. |
| APC-7, 7 mm |
18 GHz |
PTFE |
APC-7 stands for "Amphenol precision connector", 7mm. Developed in
the swinging 60s, ironically a truly sexless connector, which provides
the lowest VSWR of any connector up to 18 GHz. |
| OSP |
22 GHz |
PTFE |
OSP stands for "Omni-Spectra push-on", a blind-mate connector with zero detent. Often used in equipment racks. |
| 3.5 mm |
26.5 GHz |
Air |
A precision (expensive) connector, it mates to cheaper SMA connectors. |
| OSSP |
28 GHz |
PTFE |
OSP stands for "Omni-Spectra subminiature push-on", a smaller version of OSP connector. |
| SSMA |
38 GHz |
PTFE |
Smaller than an SMA. |
| 2.92 mm |
40 GHz |
Air |
Precision connector, developed by Mario Maury in 1974. 2.92 mm will
thread to cheaper SMA and 3.5 mm connectors. Often called "2.9 mm". |
| K |
40 GHz |
Air |
The original mass-marketed 2.92 mm connector, made by Wiltron (now
Anritsu). Named the "K" connector, meaning it covers all of the K
frequency bands. |
| GPO, OSMP, SMP |
40 GHz |
PTFE |
"Gilbert push-on", "Omni-spectra microminiature push-on" |
| OS-50P |
40 GHz |
|
Smaller version of OSP blind-mate connector. |
| 2.4 mm |
50 GHz |
Air |
2.4 mm, and 1.85 mm will mate with each other without damage.
Developed by Julius Botka and Paul Watson in 1986, along with the 1.85
mm connector. |
| 1.85 mm |
60 GHz |
Air |
Mechanically compatible with 2.4 mm connectors. |
| V |
60 GHz |
Air |
Anritsu's term for 1.85 mm connectors because they span the V frequency band. |
| 1 mm |
110 GHz |
Air |
The Rolls Royce of connectors. This connector species works up to
110 GHz. It costs a fortune! Developed at Hewlett Packard (now Agilent)
by Paul Watson in 1989. |
