Website visitor Neil S. provided the following explanations regarding connector
name origins:
C - Concelman (Carl Conselman worked
for Ampheol)
N - Neill (Paul Neill worked for Bell Labs)
TNC - Threaded Neill-Concelman
BNC - Bayonet Neill-Concelman
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

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.

| SMB (Sub-Miniature B)
OSMB
|
 |
 |
| SMC (Sub-Miniature C)
OSMC
|
 |
 |
| SSMA (Sub-SMA)
