What is RF Coaxial Connectors?


What type of SMA Connector?
SMA (SubMiniature version A) connectors are coaxial RF connectors developed in the 1960s as a minimal connector interface for coaxial cable with a screw type coupling mechanism. The connector has a 50 Ω impedance. It offers excellent electrical performance from DC to 17 GHz.

What is SMB Connectors?
SMB (SubMiniature version B) connectors are coaxial RF connectors developed in the 1960s. SMB connectors are smaller than SMA connectors.
They feature a snap-on coupling and are available in either 50 Ω or 75 Ω impedance. They offer excellent electrical performance from DC to 4 GHz.
An SMB jack has a male center pin, whilst an SMB plug has a female basket.

What is SSMB Connectors?
The SSMB connector is a small version of the standard SMB connector with a 'snap-on' coupling.
1. Impedance: 50 Ohm
2. Operating frequency: DC-12,4 GHz

What is SMZ Connectors?
The SMZ connector features the 75 ohm impedance of the Mini-SMB connector brought up to the size of the standard 50 ohm SMB.

What is SMC Connectors?
SMC (SubMiniature version C) connectors are coaxial RF connectors developed in the 1960s. They use a #10-32 UNF threaded interface (screw type) and are available in 50 Ω or 75 Ω impedances. They offer excellent electrical performance from DC to 10 GHz.

What is SMP Connectors?
The SMP interface is a subminiature interface in the same scale as MMCX connectors but offers a frequency range of DC to 26.5 GHz. It is commonly used in miniaturized high frequency coaxial modules and is offered in both push-on and snap-on mating styles.

What is N type Connectors?
Developed in the 1940's, the N-Type connector series was the first to offer true microwave performance. The N-Type connector was developed to satisfy the need for a durable, weatherproof, medium-size RF connector with consistent performance through 11 GHz.

What is BNC Connectors?
The BNC connector (Bayonet Neill–Concelman) is a common type of RF connector used for coaxial cable. It is used with radio, television, and other radio-frequency electronic equipment, test instruments, video signals, and was once a popular computer network connector. BNC connectors are made to match the characteristic impedance of cable at either 50 ohms or 75 ohms. It is usually applied for frequencies below 3 GHz [1] and voltages below 500 Volts

What is MCX Connectors?
MCX (micro coaxial) connectors are coaxial RF connectors developed in the 1980s. They have the same inner contact and insulator dimensions as the SMB connector but are 30% smaller. MCX is standardized in European CECC 22220.[1]
They use a snap-on interface and usually have a 50 Ω impedance (occasionally 75 Ω also) . They offer broadband capability from DC to 6 GHz.[2] The contact surfaces are gold-plated.

What is MMCX Connectors?
MMCX (micro-miniature coaxial) connectors are coaxial RF connectors similar to MCX but smaller. They conform to the European CECC 22 000 specification.The connectors have a lock-snap mechanism allowing 360-degree rotation and usually have a 50 Ω impedance. They offer broadband capability from DC to 6 GHz.[1]

What is TNC Connectors?
The TNC (threaded Neill-Concelman) connector is a threaded version of the BNC connector. The connector has a 50 Ω impedance and operates best in the 0–11 GHz frequency spectrum. It has better performance than the BNC connector at microwave frequencies.

What is FME Connectors?
FME (For Mobile Equipment) is a miniature 50Ω RF connector series offering excellent performance from DC to 2.0 GHz used with primarily with RG-58 or equivalent coaxial cables employed in mobile applications and installations.

What is UHF Connectors?
Mini-UHF connectors are miniaturized versions of UHF connectors, designed primarily for use in mobile phones and similar applications where size is an important consideration. Introduced in the 1970s, Mini-UHF has a 3/8-24 thread size and operates up to 2.5 GHz.[1]

What is QMA Connectors?
QMA and QN connectors are quick-connect RF connectors that were designed to replace the widely used SMA connector (used in low power transmissions; DC–18 GHz) and Type N (used in medium power transmissions; DC–11 GHz) connectors.

What is FAKRA Connectors?
FAKRA connectors are designed to perform up to 4GHz and meet the particular mechanical and environmental requirements of the automobile industry.

What is Hirose UFL Connectors?
U.FL, is a miniature coaxial RF connector for high-frequency signals up to 6 GHz manufactured by Hirose Electric Group in Japan.[1] U.FL connectors are commonly used inside laptops and embedded systems to connect the Wi-Fi antenna to a Mini PCI card. Female U.FL connectors are not designed with reconnection in mind, and they are only rated for a few reconnects before replacement is needed. The female U.FL connectors are generally not sold separately, but rather as part of a pigtail with a high-quality 1.32 mm doubly shielded cable, which allows for a low-loss connection.
