Connectors

A coaxial RF connector (radio frequency 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, blind mate) and springs for a low ohmic electric contact while sparing the gold surface, thus allowing very high mating cycles and reducing the insertion force. Research activity in the area of radio-frequency (RF) circuit design has surged in the 2000s in direct response to the enormous market demand for inexpensive, high-data-rate wireless transceivers.

SMC Connectors

SMC (SubMiniature version C) connectors are coaxial RF connectors developed in the 1960s. They use a #10-32 UNF threaded interface (screw type). They offer excellent electrical performance from DC to 10 GHz. Female SMC connectors have a pin for the center contact, and male SMC connectors have a socket for the center contact, and are therefore analogous to the "reverse polarity" versions of other types of RF connectors

SSMA Connectors

The SSMA connector is essentially a smaller version of the SMA. It was originally designed for use with .085 semi-rigid cable. The male contact was designed to be the same size as the cable conductor so that it could be used as the mating pin for optimized VSWR.

SMP Connectors

The SMP interface is a subminiature interface in the same scale as MMCX connectors but offers a frequency range of DC to 40 GHz. It is commonly used in miniaturized high frequency coaxial modules and is offered in both push-on and snap-on mating styles.

The interface is an excellent choice for PC board to board interconnects. For these applications, the interface series offers an interesting solution by utilizing a male connector on each of the PC boards and a female-to-female adapter mounted in between to complete the connection. The female adapter is often called a bullet and is necessary to provide a flexible link between the male connectors. This flexible link allows .020 inches of radial float and .010 inches of axial float. Typically, one male connector will be specified as a snap on interface and the other as a push on. This ensures that the bullet adapter remains fixed in the same male connector if the PC boards are separated. The bullets are available in multiple lengths to allow for different board spacing.

In its snap-on configuration, the SMP interface is available in two levels of detent each with different mate and de-mate forces. The two levels are full detent and limited detent. In board mount applications, the lower level of detent (limited detent) is typically selected, as it is only required to retain the bullet. Full detent is often used for discreet cable connections where higher forces are desirable.

SHV Connectors

The SHV (safe high voltage) connector is a type of RF connector used for terminating a coaxial cable. The connector uses a bayonet mount similar to those of the BNC and MHV connectors, but is easily distinguished due to its very thick and protruding insulator. This insulation geometry makes SHV connectors safer for handling high voltage than MHV connectors, by preventing accidental contact with the live conductor in an unmated connector or plug. The connector is also designed such that when it is being disconnected from a plug, the high voltage contact is broken before the ground contact, to prevent accidental shocks. The connector is also designed to prevent users from forcing a high voltage connector into a low voltage plug or vice versa, as can happen with MHV and BNC connectors.

BMA Connectors

A blind mate connector(BMA) is differentiated from other types of connectors by the mating action that happens via a sliding or snapping action which can be accomplished without wrenches or other tools. They have self-aligning features which allows a small misalignment when mating.

Usage : Electrical blind mate connectors provide power or signal and are distinguished from other connectors in that they do not feature a rigid mechanical retention mechanism belonging to the interface itself, such as a threaded coupling nut on an SMA connector. They are typically used in a multi-pin arrangement between racks and panels, daughtercard to backplane, or similar applications where the connector is not mated by itself, but rather by the action of inserting the entire unit or module.

Types
RF : Blind mate RF connectors are generally intended to be used without wrenches or other tools, but can come packaged in a multiport configuration that includes mounting hardware or provided as inserts in a circular connector such as a MIL-DTL-38999. Some examples of blind mate RF interfaces include BMA (OSP), BMMA (OSSP), SMP, and SMPM.

Certain styles of blind mate RF connectors feature a detent or undercut to allow for the mating connector to snap into, improving retention. These styles are typically used when the mate is a cable connector and might see a significant force that would normally demate the connection.

Other configurations feature a smooth bore in which the mate simply slides into to connect. These arrangements are more commonly found in board to board connections, where they are mated with a female to female "bullet" adapter, and no significant force is present to demate the connection.

Optical: Optical signals can also be connected using blind mate connectors providing the capability to link fibre optics on a plug-in card to an optical backplane, or through an optical midplane
