RF connector

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.

Types

Standard types

7/16 DIN connector, a high power 50-ohm connector originally developed by Spinner
BNC (Bayonet Neill-Concelman)
C connector (Concelman)
Dezifix connector, hermaphrodite connector used mainly by Rohde & Schwarz
GR connector (General Radio)

NMO mount (New Motorola MOunt), for removable mobile antennas. Large threaded base for durability in wind.
N connector (Neill)
SC connector, screw version of C connector
TNC connector (Threaded Neill- Concelman)
UHF connector (e.g. PL-259/SO-239) Also referred to as an "M-type" connector by Japanese manufacturers such as Kenwood
