1、What is RF cable? What is the role? ：
  RF cables are cables that transmit electromagnetic energy in the radio frequency range, RF cables are indispensable components of various radio communication systems and electronic equipment, widely used in wireless communications and broadcasting, television, radar, navigation, computers and instruments.
Product features.
1. Can transmit a wide range of frequency bands
2. High degree of defense against external interference
3. Small antenna effect, small radiation loss
4. Simple structure, convenient installation, more economical.
Product classification
RF cable structure is diverse, can be classified according to different ways and types.
(1) Coaxial RF cable
Coaxial RF cable is the most commonly used structure type. Because its inner and outer conductors are in concentric position, electromagnetic energy is confined to the medium between the inner and outer conductors
Therefore, it has the significant advantages of small attenuation, high shielding performance, wide frequency band and stable performance. Usually used to transmit 500 kHz to 18
gigahertz of radio frequency energy. At present, the commonly used RF coaxial cable has two types: 50Q and 75Q RF coaxial cable. Characteristic impedance 75Q RF
Coaxial cable is commonly used in CATV network, so called CATV cable, transmission bandwidth of up to 1 GHz, the current common CATV cable transmission bandwidth of 750
MHz.
(2) symmetrical RF cable
Symmetrical RF cable loop whose electromagnetic field is open, due to the radiation of electromagnetic energy at high frequencies, thus increasing the attenuation, and lead to shielding performance
Poor, coupled with the influence of atmospheric conditions, usually less used. Symmetrical RF cable is mainly used in the case of low RF or symmetrical feeder.
(3) spiral RF cable coaxial or symmetrical cable in the conductor, sometimes can be made into a spiral coil-like, in order to increase the inductance of the cable, thereby increasing the
Cable wave impedance and delay the transmission time of electromagnetic energy, the former is called high resistance cable the latter is called delayed cable. If the spiral coil along the length of the direction
Coiled in different densities along the length, it can be made into a variable resistance cable.
Cable role.
The cable is used to transmit radio frequency (RF) signals. It has low emission losses and provides protection from electromagnetic interference so that the signal's low power consumption will be transmitted over longer distances. Coaxial cable is composed of a core, insulation, shielding, and housing. This is called coaxial cable because these sections all have the same shaft. There are many different types of coaxial cable, each with different physical and electronic characteristics designed for specific tasks. This is commonly used to carry cable TV signals along suburban streets and in homes. Coaxial cable is used to carry television signals and connect video equipment together. It can also be used to carry radio signals and connect receivers, transmitters and antennas together. Short lengths of coaxial cable are also used to connect equipment with test equipment, such as signal generators. Coaxial cable was once widely used to connect computer local area networks (LANs), but has replaced twisted pair cable. However, cable broadband is still popular and used for the same purposes as coaxial cable cable networks. Most coaxial cable networks will eventually replace the superior fiber optic networks.

2、What is RF microwave test cable and category classification? : RF Microwave Test Cable
  RF microwave test cable: a commonly used high-precision system test supplies; RF Microwave Coax Test cable, in the field of wireless communications is a commonly used high-precision system test supplies, and test instruments supporting the connection, the most common Agilent, Rohde & Schwarz, Anrisu, etc. Vector network analyzer, frequency sweeper. Microwave coaxial test cable category can be divided into three levels; a: military aerospace grade, the main feature is the phase amplitude is very stable, resistant to high and low temperature and other environmental factors, VSWR small, while the frequency reaches 26.5Ghz, 40Ghz, 50Ghz 60Ghz, 75Ghz, 110Ghz. Economic. RF microwave cable early basically by foreign manufacturers to dominate the domestic market. According to the news, there have been only a few domestic manufacturers can be compared with foreign manufacturers such as Gore, Times Microwave Huber + suhner, Micro coax, Astrolab, IW, Megphase, Harbour, Rosenberger Radiall Molex, but because of the Most of the institutions use the habit, or some interests, excluding domestic manufacturers.

4、What are the main categories and series of RF cables and their applications and characteristics? :
 RG series.
RG series RF cables are a series of coaxial cables originally defined by the US military standard. It is widely used in various industries. With the development of cable manufacturing technology and material science and technology, different manufacturers provide equivalent coaxial cables to the market to replace RG cables.
Semi-Flexible Coaxial Cable.
Semi-flexible coaxial cables can be bent and formed by hand. They are usually made with a tin-impregnated braid and are commonly insulated with PE or FEP, or without an insulating jacket. Commonly available 50ohm semi-flexible coaxial cables are 0.047, 0.086, 0.0141, 0.0250.
Semi-steel cables.
Semi-steel coaxial cables can be formed using clamps or by making machine bends. Usually aluminum, copper or stainless steel tubing is used as the outer conductor. There is no insulation sheath.
High performance ultra-flexible microwave cable.
High-performance ultra-flexible microwave cables have stable phase characteristics as well as amplitude characteristics. High stability over the range of mechanical dynamic applications and over the range of temperature variations.
Low-noise cables.
Low-noise cables are distinguished from ordinary coaxial cables by minimizing the electrostatic noise generated by the cable itself. It is commonly used for sensitive and weak signal measurements.
Bellows Coaxial Cable.
Bellows cables use hollow copper tubes as inner conductors and corrugated copper or aluminum tubes as outer conductors. It has low loss and high power characteristics.
Flexible cables.
Electrical performance can replace semi-steel or semi-flexible .86" and .141" equivalent, with flexible characteristics to meet dynamic applications and multiple repetitive bending.
Leakage coaxial cable.
Leakage cable is a coaxial cable with a radiating window in the outer conductor, which can act as an antenna while transmitting signals. It is commonly used for signal coverage in tunnels, indoors, inside locomotives, cabins, etc.
Low loss RF cable.
Low loss RF cables usually use low density PTFE as the insulation medium and single core conductor as the inner conductor.
Low smoke and halogen-free RG cable.
The use of environmentally friendly low smoke and halogen-free sheath, can replace the standard RG cable.
Tri-coaxial cable.
Tri-coaxial cables are similar in construction to ordinary coaxial cables. It has three concentric layers of conductors and is separated by an insulator. It is commonly used for metrology testing and video transmission.
Flexible semi-rigid cable.
Flexible semi-rigid cable is a typical semi-rigid cable with the same physical structure, using a specially treated seamless copper tube as the outer conductor, which distinguishes its bending characteristics from semi-rigid cable and has flexible characteristics, while maintaining the stable amplitude and phase characteristics of semi-rigid cable.
