Radiofrequency leakage: <\/strong>-90dB\/minute between 2 and 3 Gigahertz frequencies.<\/li>\n<\/ul>\n\n\n\nKey applications:<\/h4>\n\n\n\n
Most wireless devices and GPS systems primarily use SMA connectors for some decades. <\/p>\n\n\n\n
You can use them with flexible or semi-rigid coaxial antenna cables. <\/p>\n\n\n\n
There are PCB mountable jacks to mount the SMA antennas to their circuit boards. <\/p>\n\n\n\n
Most cellular antennas used in cellular networking use SMA connectors due to their consistent performance at high frequencies, small size, and robust nature. <\/p>\n\n\n\n
On torquing with a wrench, the connection becomes weatherproof and is suitable for several outdoor conditions. <\/p>\n\n\n\n
Due to the growing wireless networking, SMA connectors are also common in Wi-Fi antennas.<\/p>\n\n\n\n
RP-SMA connector:<\/h3>\n\n\n\nDescription: <\/h4>\n\n\n\n
The -Reverse Polarity-SMA connector is a form of the normal SMA connector. <\/p>\n\n\n\n
It is similar to the standard version in its physical, electrical, and mechanical performance. <\/p>\n\n\n\n
However, the only difference lies in the inner mating interfaces, reversed in RP-SMA. <\/p>\n\n\n\n
It means the internal male pin found in the standard male SMA connector is located in the female RP-SMA connector, and the female counterpart is found in the male RP-SMA connector. <\/p>\n\n\n\n
As the gender polarity changes in the RP-SMA connector, it is named the Reverse polarity-SMA connector.<\/p>\n\n\n\n
In the 1990s, as consumer wireless devices grew, the US Federal Communications Commission developed this connector to prevent illegally connecting consumer devices to high-gain antennas. <\/p>\n\n\n\n
The connector may look like an SMA connector with reverse polarity but cannot form an electrical connection with an SMA connector. <\/p>\n\n\n\n
As a result, it became easy to classify professional grade and consumer products.<\/p>\n\n\n\n
Physical specifications<\/h4>\n\n\n\n
Like an SMA connector, it is also a threaded connector that connects through screw coupling. <\/p>\n\n\n\n
Like a standard SMA connector, it has 36 threads\/inch, which tightens through a hex nut. <\/p>\n\n\n\n
The same materials and fabrication procedures are used in manufacturing as in standard SMA connectors.<\/p>\n\n\n\n
It has two complementary parts:<\/p>\n\n\n\n
\n- MALE RP-SMA<\/strong> has internal threads and a hex nut but a female mating interface, as described above.<\/li>\n\n\n\n
- Female RP-SMA<\/strong> has a barrel with external threads and a male central pin.<\/li>\n<\/ul>\n\n\n\n
Electrical specifications<\/h4>\n\n\n\n\n- Frequencies: <\/strong>can support frequencies up to 18 Gigahertz, mostly in wireless applications.<\/li>\n\n\n\n

- The electrical performance<\/strong> of the RP-SMA connector is the same as that of a standard SMA connector.<\/li>\n<\/ul>\n\n\n\n
Key applications:<\/h4>\n\n\n\n
Reverse polarity-SMA connectors are standard in Wi-Fi antennas and their related hardware, and you can commonly find them in consumer wireless networking devices.<\/p>\n\n\n\n
N-type connector<\/h3>\n\n\n\nDescription:<\/h4>\n\n\n\n
An electrical engineer, Paul Neill, developed this N-type connector in 1940. <\/p>\n\n\n\n
It is a sizable hard-wearing connector effective in microwave radio frequency transmission in different external conditions. <\/p>\n\n\n\n
Contemporarily, it is termed type-N and is interchangeable with the original one.<\/p>\n\n\n\n
This threaded connector\u2019s performance and design are consistent in antennas and RF circuits working at 50 and 75 ohms.<\/p>\n\n\n\n
This connector\u2019s capability to accommodate different coax cable diameters is useful.<\/p>\n\n\n\n
Physical specifications:<\/h4>\n\n\n\n
You can find the specifications of the Type N connector in Military Standard 348.<\/p>\n\n\n\n
The connector has an inner pin\/socket working as a central conductor, and the outer conductors separate the inner conductors through an air gap. <\/p>\n\n\n\n
The conductors are made of gold\/silver plating. <\/p>\n\n\n\n
Some connectors also have rubber gaskets for extra waterproofing.<\/p>\n\n\n\n
Its two complementary components are:<\/p>\n\n\n\n
\n- Male: <\/strong>the N-male has a central pin with internal threads.<\/li>\n\n\n\n
- Female: <\/strong>the N-female has an inner socket with external threads, and the male pin inserts into the female socket to set up an electrical connection.<\/li>\n<\/ul>\n\n\n\n
The hand tightening works for the barrel of the N-male type; however, some may have hex nuts too. <\/p>\n\n\n\n
The connector is rated for 500 mating cycles when properly mated through its \u215d-24 threaded coupling. <\/p>\n\n\n\n
Do not mismatch the 50 and 75-ohm variants, as it may damage the connector.<\/p>\n\n\n\n

Additionally, they are also common in industries in testing and measurement applications. <\/p>\n\n\n\n
Antenna connections that demand ruggedness, capacity to bear vibrations, and repeated connection and disconnection use these connectors. <\/p>\n\n\n\n
Recently, the connector is also finding its use in wireless networking applications as some variants of Type N can also support corresponding frequencies of up to 18 Gigahertz.<\/p>\n\n\n\n
M`MCX connector:<\/h3>\n\n\n\nDescription:<\/h4>\n\n\n\n
MMCX stands for micro-miniature coax connectors. <\/p>\n\n\n\n
These are snap-on connectors that allow 360-degree rotation and the antenna connection. <\/p>\n\n\n\n
These are a smaller version (35% smaller) of the MCX connectors and were developed in the 1990s. <\/p>\n\n\n\n
These robust connectors follow CECC22220 specifications. <\/p>\n\n\n\n
Despite being so small, these connectors have maximum rating cycles of up to 500.<\/p>\n\n\n\n

Due to their small size, they are also ideal for size and weight-restricted applications. <\/p>\n\n\n\n
Further, their capacity to fit in dense circuit boards and robust nature make them fit for internal antenna use.<\/p>\n\n\n\n
TNC connector:<\/h3>\n\n\n\nDescription:<\/h4>\n\n\n\n
TNC or threaded Neill Concelman is similar to the BNC connector but with threads. <\/p>\n\n\n\n
Due to their threaded nature, these medium-sized connectors ensure secure coupling, making them suitable for microwave frequencies.<\/p>\n\n\n\n
Physical specifications:<\/h4>\n\n\n\n
The fabrication of the TNC connector follows MIL-C-39012 specifications. Its diameter is around \u00bd an inch. <\/p>\n\n\n\n
The body is made from brass, and the inner female receptacle is made from beryl copper, while the male center pin with brass. <\/p>\n\n\n\n

You can also use them to terminate various coaxial cable types.<\/p>\n\n\n\n
RP-TNC connector:<\/h3>\n\n\n\nDescription:<\/h4>\n\n\n\n
The RP-TNC is a variant of the TNC connector with the same functionality but with reverse gender polarity. <\/p>\n\n\n\n
Due to reverse polarity, an RP-TNC connector looks similar to a TNC connector but cannot form an electrical connection. <\/p>\n\n\n\n
Thus, it is also necessary that while using TNC and RP-TNC connectors, you must examine them carefully for correct pairing.<\/p>\n\n\n\n
Physical specifications:<\/h4>\n\n\n\n
RP-TNC is also a 7\/16-28 threaded mating connector with PTFE surrounding the central conductors. <\/p>\n\n\n\n
The male RP-TNC has internal threads with a female receptacle instead of a male central pin, while the female RP-TNC has externalized threads with a male center pin instead of a female receptacle. <\/p>\n\n\n\n
The mating is through screw coupling with a maximum rating of 500 cycles.<\/p>\n\n\n\n
Electrical specifications:<\/h4>\n\n\n\n
RP-TNC connectors also have the same electrical performance as TNC connectors.<\/p>\n\n\n\n
Key applications:<\/h4>\n\n\n\n
The RP-TNC connectors are suitable for consumer wireless devices and systems, and the reverse polarity prevents the illegal connection of professional-grade equipment to consumer devices. <\/p>\n\n\n\n
They are commonly used in cellular networking, base stations, Wi-Fi testing, radar, and testing & measurement.<\/p>\n\n\n\n
U. FL connector:<\/h3>\n\n\n\nDescription:<\/h4>\n\n\n\n
U. FL is a miniature RF conductor in PCI cards and internal antennas. <\/p>\n\n\n\n
Its low profile and small mounting surface make it suitable for applications with small spaces. <\/p>\n\n\n\n
During connection, it gives a click sensation. <\/p>\n\n\n\n
It is also capable of supporting microwave frequencies. <\/p>\n\n\n\n
Physical specifications:<\/h4>\n\n\n\n
These connectors have a phosphor bronze shell with liquid polymer as an insulator. <\/p>\n\n\n\n
The central conductor is bronze or brass. <\/p>\n\n\n\n
The male version often works as a PCB-mounted jack with a central pin, while the female version presses onto the male pin and has a central receptacle. <\/p>\n\n\n\n
These connectors only have 30 mating cycles, so they are unsuitable for frequent connection-disconnection.<\/p>\n\n\n\n
