What does RP SMA stand for?

reverse polarity
RP-SMA stands for “reverse polarity” (sometimes also referred to as reverse SMA or for short “R-SMA”). It is designed to prevent the unauthorized connection of an external antenna to increase the range. In an RP-SMA connector, the gender has been changed.

What is SMA coaxial cable?

The abbreviation SMA stands for “Sub-Miniature Version A”. In order to maintain the transmission speed of coaxial cables, both versions of the corresponding connectors have a coaxial design. They therefore have good electrical shielding and low electromagnetic interference.

Is SMA the same as 3.5 mm?

SMA and 3.5mm are matable connectors. The SMA connector is an economical, lower performance interface. 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.

Is SMA the same as F?

SMA connectors must not be confused with the standard household 75-ohm type F coax connector (diameters: male 7⁄16 inch (11 mm) circular or hex; female 3⁄8 in (9.5 mm) external threads), as there is only about a 2 mm difference overall in the specifications.

Why are SMA connectors so expensive?

The expensive places(farnell) are expensive because the components they carry are specificed into the smallest of details. The stuff at dealextreme is without documentation of any sort.

Is coax a BNC?

The BNC (Bayonet Neill–Concelman) connector is a miniature quick connect / disconnect radio frequency connector used for coaxial cable. It features two bayonet lugs on the female connector; mating is fully achieved with a quarter turn of the coupling nut.

What is Rp male?

The term “reverse polarity” refers only to the gender of the connector’s contact pin, not in any way to the signal polarity. A RP-SMA(F) connector is a JACK type – has outside threads – but has an inner pin (hence reversed), and male RP-SMA connector has inside threads and a center receptacle.

Is coaxial the same as BNC?

The BNC (Bayonet Neill–Concelman) connector is a miniature quick connect / disconnect radio frequency connector used for coaxial cable. BNC connectors are most commonly made in 50 ohm and 75 ohm versions, matched for use with cables of the same characteristic impedance.

Does 2.4-mm mate with SMA?

At first glance, it may be difficult to distinguish a 2.4-mm connector from a 2.92-mm connector. However, should one attempt to connect a 2.4-mm connector to an SMA connector, the difference will be very clear—the two connector types will not mate.
