Product Overview
The model of SMA male connector solder is SMA-JB3.SMA series are popular 50 ohms RF connectors, using a threaded interface, providing reliable and excellent electrical performancein high frequencies. They are widely used in aero and aero space, military weapons, wireless network, and microwave devices ordata communication. They also attach semi-flex or semi-rigid cables working up to 18GHz.
SMA Connector Cable Characteristics
1) Due to its low shielding performance, TV cables are typically used in systems where impedance is the only consideration. A typical application is TV antennas.
2) TV flexible cables are a variation of TV cables. They offer relatively continuous impedance and good shielding, are bendable, and are inexpensive. They are widely used in the computer industry, but not in systems requiring high shielding performance.
3) Shielded flexible cables eliminate inductance and capacitance and are primarily used in instruments and buildings.
4) Flexible coaxial cables are the most common sealed transmission cables due to their unique properties. Coaxial means that the signal and ground conductors are on the same axis, and the outer conductor is made of a fine braided wire, hence the name braided coaxial cable. This cable provides excellent shielding of the center conductor. The shielding effectiveness depends on the braid type and braid thickness. In addition to its high-voltage resistance, this cable is also suitable for use under high-frequency and high-temperature conditions.
5) In addition to its high-voltage resistance, this cable is also suitable for use under high-frequency and high-temperature conditions. 6) Semi-rigid coaxial cable uses a tubular shell instead of a braided layer, which effectively makes up for the disadvantage of poor shielding effect of braided cable at high frequencies. Semi-rigid cable is usually used when the frequency is very high.
