For that reason and that they are just rated for a limited number of connection cycles, an SMA connector is not usually a good choice for metrological applications. Variability in the construction and the mating of the connectors limits the repeatability of the connector impedance. The SMA connector uses a polytetrafluoroethylene (PTFE) dielectric that contacts along the mating plane. ![]() There are also reverse-polarity ("RP") SMA connectors in which the pin and sleeve are swapped so that the "male" RP-SMA has a center sleeve surrounded by an inside-threaded barrel, and the "female" RP-SMA has a center pin and an outside-threaded barrel. As with most other connectors, the gender assignment corresponds to the innermost electrical component. The centre pin is the same diameter as the centre of RG402 Coax so that connections can be made with no discontinuity, forming the pin from the coax itself. The male is equipped with a hex nut measuring 5⁄ 16 inch (0.3125 inch / 7.9 mm) across opposite flats, thus taking the same wrench as a #6 SAE hex nut.Ī standard-polarity SMA male connector has a 0.9mm diameter center pin surrounded by barrel with inside threads, and the standard SMA female connector has a center sleeve surrounded by a barrel with outside threads. The SMA connector employs a 1⁄ 4 inch diameter, 36-thread-per-inch threaded barrel. The interface dimensions for SMA connectors are listed in MIL-STD-348. It is also commonly used in radio astronomy, particularly at higher frequencies (5 GHz+). The SMA connector is most commonly used in microwave systems, hand-held radio and mobile telephone antennas and, more recently, with WiFi antenna systems and USB software-defined radio dongles. There are also mechanically compatible connectors such as the K-connector which operate up to 40 GHz. ![]() SMA was originally designed for use from DC (0 Hz) to 12 GHz, however this has been extended over time and variants are available to 18 GHz and 26.5 GHz. SMA ( SubMiniature version A) connectors are semi-precision coaxial RF connectors developed in the 1960s as a minimal connector interface for coaxial cable with a screw-type coupling mechanism. Standard male SMA connector: male body (inside threads) with male inner pin In addition to the right-angle SMA connector which is available in standard and reverse polarity variants, a new rear mounted, 6GHz reverse polarity N Type bulkhead jack has also joined the Nautilus line up.Figure 1. “Combined with our expertise in the market with IP-rated cable assemblies, Nautilus will remain at the forefront with new and innovative configurations that are suitable for a wide range of applications as we continue to develop the range.” “Providing flexibility for our customers with a wealth of product choice has always been one of our key objectives,” said Andy Hamlin, Global Sales and Distribution Manager. ![]() SMA right-angle configurations can really help with placement in some designs where the position of other components make it difficult to route a standard straight cable. ![]() To further expand its range of higher frequency IP rated cable assemblies, GradConn has introduced new 6 GHz right-angled SMA connectors to the Nautilus product line up.Ī first to market product, this gives engineers even more options when looking for water and dust-proof coaxial connections in their designs, with new 6 Ghz capabilities catering for the latest technology trends such as 5G and IOT applications. ![]()
