What is RP SMA cable?
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. The RP-SMA male is also the connector with inside threads, but it has the metal sleeve as an inner conductor.
Is RP SMA compatible with SMA?
What is the difference in these two? Reverse polarity SMA (RP-SMA or RSMA) is designed to be incompatible with standard SMA connectors to comply with U.S. FCC regulations which seek to prevent consumers from attaching non-standard aerials to wireless devices.
Are all SMA connectors the same size?
The SMA female connector is identified by outside 1/4″-36 threads. A standard polarity connector will have a female sleeve. The RP SMA male connector is identified by inside 1/4″-36 threads and a 5/16″ hex nut.
What is a reverse polarity SMA connector?
Reverse polarity SMA (RP-SMA) is a variation of the SMA connector specification which reverses the gender of the interface, as shown in Figures 1-4 below. The term “reverse polarity” refers only to the gender of the connector’s contact pin, not in any way to the signal polarity.
What does SMA mean in electronics?
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.
What is SMA coax connector?
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 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.
What is SMA size?
1/4-inch
Connector design The SMA connector employs a 1/4-inch diameter, 36-thread-per-inch threaded barrel. 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.
Are all SMA connectors 50 ohm?
SMA connectors are designed to have a constant have a 50 ohm impedance across the connector. The SMA connectors were originally designed and specified for operation up to 18 GHz, although some versions have top frequencies of 12.4 GHz, some les and some are specified up to 24 or 26.5 GHz.
What is SMA thread?
SMA and RP-SMA are standard threaded antenna connectors for high frequency applications from 1 GHz to approx. 16 Ghz. They are most commonly used in microwave systems, such as portable radio and mobile phone antennas, but also with WiFi antenna systems.
How does a SMA connector work?
The SMA connector uses a polytetrafluoroethylene (PTFE) dielectric that contacts along the mating plane. Variability in the construction and the mating of the connectors limits the repeatability of the connector impedance.
What kind of connector is a RP-SMA?
RP-SMA is a round screw-type connector, with medium-sized, threaded coupling connectors that are rated for frequencies from the lowest (DC) up to 18GHz. We offer an RP-SMA wrench to assist in installing antennas, cables and adapters with RP-SMA or SMA connector (s).
How tall is the male to female RP-SMA cable?
Male To Female RP-SMA Extension Cable: Outdoor-Rated RG174U: 3-FT & 6.5-FT options. Male to Female RP-SMA Extension Cable: 6.5FT, 8FT, 10FT. Male to Female Low Loss Shielding
How is the gender determined on a RP-SMA?
The gender is referring to the pins inside–not the threads. RP-SMA male has threads on inside. RP-SMA male has a socket inside rather than a pin, as you might expect, because the RP stands for “Reverse Polarity.” The socket/pin configuration is female when it appears to be male, and vice versa. More details regarding RP-SMA gender determination.
Which is the reverse polarity SMA connector specification?
Reverse-polarity SMA (RP-SMA or RSMA) is a variation of the SMA connector specification that reverses the gender of the interface, as shown in Figures 1 and 2.
