What does SMA stand for in connectors?

SubMiniature Version A Connector
What Does SubMiniature Version A Connector (SMA Connector) Mean? An SubMiniature version A (SMA) connector is a coaxial cable connector developed in the 1960s as a semi-precision minimal connector interface with a screw-type coupling mechanism for coaxial cables.

Are SMA and F connectors the same?

The SMA connector(SubMiniature version A) is a 50 ohm coaxial connector. It is visually similar to an F type connector that is commonly used for audio/video communication, but has different dimensions, mechanical properties and is used for different applications such as RF communications up to 18 GHz.

What type of connector is SMA?

semi-precision coaxial RF connectors
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. The connector has a 50 Ω impedance.

Is SMA compatible with 3.5 mm?

The SMA connector is mechanically compatible with two other connector types: 3.5- and 2.92-mm connectors. Both of these employ an air dielectric and can perform at higher frequencies than their SMA counterpart.

Is K connector compatible with SMA?

Yes. SMA, 3.5mm, and 2.92mm (K) connectors all have similar mechanical characteristics which allows them to be mated to each other. However, because the dimensions of each connector are slightly different the connection is not ideal and does result in degraded electrical performance.

How many MM is a SMA connector?

It is easy to see which type a connector is by looking at the material surrounding the center pin. SMA type will have a foam bead, while 3.5mm uses an air interface. Due to cost, the 3.5mm connector is most often used in metrology applications, whereas the SMA connector is used for production.

What mates with what SMA?

A properly made new SMA will also mate with 2.92 & 3.5’s; however, a damaged sma connector, or a used sma connector that has a slightly bent pin, can destroy a 3.5 or 2.92 connector.

Are SMA and 3.5 mm the same?

SMA and 3.5 mm RF connectors are very similar and should be mechanically compatible, but do have some electrical differences that may be important for your application. For best performance, use SMAs with SMAs and 3.5 mm connectors with 3.5 mm connectors.

What is Amphenol connector?

The term Amphenol connector refers to various electronics connectors that are introduced, or made primarily by Amphenol Corp. Depending on the area of electronics concerned, it may refer specifically to: MIL-DTL-5015 / MIL-C-5015, a circular connector. MIL-DTL-26482 / MIL-C-26482, a circular bayonet connector.

What are N type connectors used for?

The N connector (also, type-N connector) is a threaded, weatherproof, medium-size RF connector used to join coaxial cables. It was one of the first connectors capable of carrying microwave-frequency signals, and was invented in the 1940s by Paul Neill of Bell Labs, after whom the connector is named.

Are SMA and 3.5 mm same?

Can 3.5 mm connect to SMA?

It has been established that a 3.5 mm-to-SMA mated interface is an acceptable and intended practice, per the 3.5 mm connector design.

Where are Amphenol connectors used?

RJ21, used in aggregated telecommunications cabling. Micro ribbon, used in personal computer’s connection to printer or SCSI equipments. ARINC 828, a repurposing of MIL-DTL-38999. UHF connector, a threaded RF coaxial connector.

What is the difference between SMA and 3.5 mm?

SMA type will have a foam bead, while 3.5mm uses an air interface. Due to cost, the 3.5mm connector is most often used in metrology applications, whereas the SMA connector is used for production. Because of this, it is not uncommon to see wear and tear degrade the SMA to the point of damaging mated connectors.
