	BMA / BMMA		BMA connectors feature a push-on interface and a thread less outer ground connection. They can withstand both radial and axial misalignment. BMMA connectors are miniature BMA connectors.
	BNC		Bayonet Neil-Councilman (BNC) connectors were designed for military applications, but are used widely in video and RF applications to 2 GHz. BNC connectors have a slotted outer conductor and a plastic dielectric that causes increasing losses at higher frequencies. BNC connectors are usable above 4 GHz as long as the slots radiate signals; however, these devices may not be mechanically stable to 10 GHz. Both 50Ω and 75Ω BNC connectors are available. BNC connectors are also known as bayonet navy connectors or baby Neil connectors.
	Type C		Type C connectors are medium-size, weatherproof devices with a two-stud bayonet coupling. They provide constant 50Ω impedance and may be used with 75Ω cable below 300 MHz
	Type F		Type F connectors have a screw-type coupling and frequency range up to 1.5 GHz. Applications include CATV, TV, and antennas.

	4-hole Flange Mount		Flange mounted connectors are attached to panels by bolting the flange or riveting it in place through the four holes in the flange surface.
	PC Mount		Connectors directly attach to the printed circuit board through pre-drilled holes in the board. Soldering permanently attaches connectors to PCB traces.
	Receptacle / Dummy Receptacle		Connectors with receptacle mounting are used in applications where the connector is required to fit a panel cutout. Dummy receptacles are receptacles that do not have provisions for attaching conductors. They are generally used for storage of a cable assembly connector plug.
	In-line or Cable Receptacle		Intended for cable connecting - typically mated with a straight or 90-degree plug.
	Jam Nut Receptacle		Intended for "D" shaped holes.
	Solder / Weld Mount Receptacle		Intended for higher-pressure systems and permanent mounting.
	Surface Mount (SMT)		Surface mount technology (SMT) places small components on the surface of a printed circuit board. Soldering permanently attaches connectors to PCB traces. Unlike PC mount connectors, however, SMT connectors do not require drilled holes in the PCB. Using smaller components allows for higher frequencies of operation, smaller board size, etc.
	Wall or Box Mount Receptacle		Typically flanged and threaded for an accessory (backshell) and intended for permanent mounting.
