MMCX Connector?

The MMCX connector is a coaxial radio frequency connector that complies with the European Electronic Components Committee 22000 transmission specification.

The MMCX interface was developed in the 1990s and adopts a plug-in clamp connection method that can rotate 360 ​​degrees.

Micro-miniature coaxial (MMCX) connectors are coaxial RF connectors similar to MCX but smaller. They conform to the European CECC 22000 specification. MMCX connectors are rated to 500 pairing cycles.

Usually, its characteristic impedance is 50 ohms. The MMCX interface is commonly found in the antenna interface on the wireless PC card of the personal computer and on the GPS communication antenna socket of some PDAs and GPS navigation devices. On some in-ear headphones, the MMCX interface is also used to change the data line.

Coaxial cable

A coaxial cable is a kind of wire and signals transmission line. It is generally made of four layers of materials: the innermost is a conductive copper wire, the outside of the wire is surrounded by a layer of plastic (for insulators and dielectrics), and the outside of the insulator has a thin layer.

Net-shaped conductor (usually copper or alloy), and then the outermost insulating material is used as the outer skin of the conductor. According to the size, the coaxial cable has different standard specifications, ranging from 1/8 inch to 9 inches in diameter.

Cable Types

According to the different insulation mediums, the inner and outer conductors are mainly divided into:

The foam-insulated radio frequency coaxial cable, according to the transmission properties, is divided into transmission cables and leaky cables (LCX).

Transmission cables are ordinary feeders, mainly used for radio frequency signal transmission, while leaky cables have hundreds or thousands of small holes (or slots) on their outer conductors.

These holes correspond to many radio frequency emission points so that the power can be Multi-point radiation along the cable, which integrates signal transmission and signal transmission and reception functions.

It has the dual functions of coaxial cable and antenna. It is specially used for some roads, railway tunnels, subways, buildings, mines, large exhibition halls, or airports Areas where wireless signal propagation is limited and difficult to cover.

Currently, foam-insulated radio frequency coaxial cables are mainly used as radio frequency signal transmission cables for cellular mobile communication systems such as GSM, CDMA, UMTS, LTE, etc. In addition, there are also other applications, such as the connection between antenna arrays, radiofrequency Connection, or jumper between the equipment and indoor coverage system.

Foam insulated cable

The insulators of the foam-insulated cables are made of physically foamed polyethylene materials; foam-insulated cables are generally used in the telecommunications industry.

Air-insulated cable

Air insulation means that the insulating medium between the inner and outer conductors is air, and the inner conductor is spirally supported by an insulating solid medium between the inner conductor and the outer conductor. Air-insulated cables are generally used for various high-power radio frequency transmissions.

According to the shape of the outer conductor, coaxial cables are divided into:

Corrugated coaxial cable. Generally speaking, corrugated cables have better flexibility and reliability, and the bending radius performance is better than straight walls. Therefore, corrugated tube outer conductor coaxial cables are mainly used in the industry.

Straight wall coaxial cable

According to different outer conductor materials, the current transmission cables are mainly divided into two categories: copper feeder and aluminum feeder. Aluminum cable has a relatively good cost advantage because of its huge price fluctuations relative to international copper prices and relatively small price fluctuations.

Since the inner conductor of the aluminum cable still uses copper as the propagation medium, its electrical performance is equivalent to that of the copper outer conductor cable, and operators are slowly accepting this new feeder type.

Terminal

Coaxial terminal, or connector. It can be regarded as a short, rigid cable. It must be designed with the same standard impedance as the cable, and the RF signal will not penetrate or lose from the interface. High-quality cables are often silver-plated or gold-plated, and lower-quality cables are also tinned. Although silver is easily oxidized, silver oxide is also conductive, so it will not affect the effect too much when it is old.

Application of coaxial cable

Short-distance coaxial cables are generally used in home audio-visual equipment or amateur radio equipment. In addition, it was once widely used in an Ethernet connection until it was replaced by a twisted pair.

Long-distance coaxial cables are often used as TV signal lines in radio or TV station networks. In the future, there will be a trend of being gradually replaced by other high-tech equipment, such as optical fiber, T1/E1, artificial satellites, etc. However, because coaxial cables are relatively cheap and have already been laid, they are still in use today.Foam-insulated coaxial transmission cable

Radiofrequency

Radiofrequency, also known as high frequency, is an oscillating frequency in the range of 3 kHz to 300 GHz. This frequency is equivalent to the frequency of radio waves and the frequency of alternating current carrying radio signals.

RF is usually used to refer to electronic oscillations, not to mechanical oscillations. However, mechanical radio frequency systems still exist (such as mechanical filters and radio frequency microelectromechanical systems).

Although radio frequency is used by definition to refer to a frequency, in daily use, it is often used as a synonym for radio to describe wireless communication systems, such as radio frequency identification.

Among the radio frequency allocations defined by the International Telecommunication Union:

Very low frequency (VLF): 3~30 kilohertz (kHz)

Low frequency (LF): 30~300 kilohertz (kHz)

Intermediate frequency (MF): 300~3000 kilohertz (kHz)

High frequency (HF): 3~30 MHz (MHz)

Very high frequency (VHF): 30~300 MHz (MHz)

Ultra-high frequency (UHF): 300~3000 MHz (MHz)

Super-high frequency (SHF): 3~30 GHz (GHz)

Extremely high frequency (EHF): 30~300 GHz (GHz)
