SMA Extension Cables: 3-inch to 6-feet
SMA Male to Female Cables: Three Inches to Six Feet
SMA extension cables are lengths of coaxial cable that are terminated with SMA connectors at both ends. These cable lengths are used for signal conduction and connectivity between antennas, cable, and radio components that carry a complementary SMA connector. Most coaxial cable extension cable-assemblies vary in length from a few inches to tens of feet.
Extension cables provide an effective way of adding to the length of signal transmission cables; extending the transmission distance between connected radio circuit components. They are passive components that receive and send the signal between two points. Ideally, SMA connector cables should be kept as short as possible to limit signal attenuation along the line.
These SMA extension cables use stand standard connectors and cables and will work with any compatible SMA connector.
The SMA connector is one of the most widely used radio frequency connectors. This brass subminiature connector is threaded and is mated by screw-coupling.
- The male SMA connector have a hex nut for tightening the connector on its body. Its threads are internal and it has an inner conducting pin.
- The female SMA connector has externalized threads and its inner mating interface has a beryllium copper connector.
The SMA connector provides excellent impedance matching at 50 ohms with exemplary power handing and signal conduction. When paired with a high-quality low-loss coax this cable provides fast efficient signal transfer with minimal attenuation.
Applications of SMA extension cables
With an operating frequency range of 0 to 18 GHz, SMA connector cables are highly versatile. They are often used in telecommunications or as antenna cables for a range of antenna classes.
Key applications of SMA extension cables include:
- Cellular networking: GSM, CDMA, 4G/LTE, 5G
- Ham radio
- Satellite and radio astronomy
- Testing and measurement
- LNAs and other radio frequency power amplifiers
- RF isolators
- Radio communication boards
LMR-100 coaxial cable - facts and figures
Most of our SMA Extension Cables in the length-range 3-inch to 6-feet, we make with LMR-100-equivalent coaxial cable
Used for transmission of radio frequency signals over antenna cables, the LMR-100 is a workhorse in connectivity over distance. Most common uses are:
- broadband internet networks
- audio visual projects
- computer networks
The LMR-100's features have much in common with other cables within it's class, here are the highlights:
- Copper clad-steel conductor - an efficient and effective vehicle for conveying radio frequency signals
- Dielectric PE foam - insulation layer keeping the signal charge from escaping the cable
- Double shielding - aluminum and copper braiding combination layers for eliminating EMI
- Outer Jacket - maintaining physical integrity in most environments
So, what is the LMR-100 actually made of:
1. Inner conductor
- LMR-100 conductor: 0.46 mm (0.02 in) in diameter
2. Dielectric foam diameter & material
- LMR-100 foam diameter: 1.52 mm (0.01 in), Polyethylene foam
3. Inner shield
- LMR-100 inner shield: aluminum tape
4. Outer shield
- LMR-100 outer shield: copper braiding
5. Outer cable sheath diameter, material & color
- LMR-100 cable sheath: 2.79 mm (0.1 in) in diameter, PVC, black
LMR-100 and it's behavior
Temperature stability = able to withstand temperatures of 85-degrees C the LMR-100 is innately resistant to relative extreme environmental heat. A temperature low of -40-degrees C. Bending radius = flexibility will be your friend with the LMR-100. It will give you the benefit of the tightest bend radius in your chosen application environment: 0.25 inches (6.4 mm) Weight = a very conservatively proportioned product, the LMR-100 proposes great logistical benefits with a weight of only: 0.0092 lb/ft (0.014 kg/m) LMR-100 is made from halogen-free components.
An all-rounder with outstanding conservative features making it a low loss champion among RF signal cables:
At 900 MHz
- LMR-100 = 0.75 dB/m. (0.228 dB/ft.)
At 2400 MHz
- LMR-100 = 1.28 dB/m. (0.389 dB/ft.)
At 3500 MHz
- LMR-100 = 1.58 dB/m. (0.48 dB/ft.)
At 5800 MHz
- LMR-100: 2.10 dB/m. (0.641 dB/ft.)
LMR-100 and double shielding
The LMR-100 internal structure benefits from double shielding. An inner aluminum layer provides 100% coverage minimizing attenuation. An outer copper braiding aides with greater thickness for the ultimate dampening effect on signal seepage.
