These are similar to the SMA connector, but with the geometries incompatibly scaled.

A taper permits minimizing the radius so that an SMA connector can be used.

The WL400 however uses standard SMA connectors for its antennas.

An electrical connection is made to the bottom of the fluid cell via a shielded SMA connector.

For that reason, an SMA connector is not a good choice for Metrology applications.

However, the precision connector can be easily damaged when mating with low-grade SMA connectors.

SMA connector, including variants:

SMA connectors are rated for up to 500 mating cycles, but to achieve this it is necessary to properly torque the connector when making the connection.

SMB connectors are smaller than SMA connectors.

The SMA connector uses a polytetrafluoroethylene (PTFE) dielectric which will contact along the mating plane.

For that reason and the fact they are just rated for a limited number of connection cycles, an SMA connector is not usually a good choice for metrological applications.

SMA connector, SubMiniature version A - also listed below in SubMiniature - is a very popular lab equipment standard connector.

The QLS (Quick Lock Standard) is a quick locking replacement for the threaded interface of the popular SMA connector.

On some directional couplers, the main line is designed for high power operation (large connectors), while the coupled port may use a small connector, such as an SMA connector.

Reverse polarity SMA connector (RSMA or RP-SMA)

Mini-QMA is a MINI version quick lock SMA connector, released by Anoison Electronics Ltd. in 2007.

The SMA connector is typically rated for mode-free operation from DC to 18 GHz, though some proprietary versions are rated to 26.5 GHz.

Eventually, the high cost of the connector led to it being obsoleted by the much more common BNC connector and, for high-frequency applications, N connectors and SMA connectors.

Reverse polarity SMA (RP-SMA or RSMA) is a variation of the SMA connector specification which reverses the gender of the interface, as shown in Figures 1 and 2.

The female RP-SMA connector has the same external housing as a standard or conventional female SMA connector, which consists of an outer shell with the threads on the outside; however, the center receptacle is replaced by a male pin.

RP-SMA connectors were introduced to separate professional and commercially available equipment, preventing unintentional or intentional connection of high-gain professional antennas with SMA connectors and commercial wireless equipment with RP-SMA connectors, violating federal or international laws.
