Types of SMB Connector：

 

 

By Gender

SMB connectors are designed with specific gender configurations to ensure proper mating:

Jack SMB Connectors: The contact is a center pin.
Plug SMB Connectors: The contact is a center receptacle.

By Mounting Method

SMB connectors are available in various mounting styles to accommodate different installation requirements:

Cable-Type SMB Connectors: These connectors are designed to terminate coaxial cables. They are available in crimp, solder, or clamp termination styles.
Panel Mount SMB Connectors: These are mounted directly onto panels or enclosures via threaded nuts, providing a fixed interface for external connections. They can be categorized into bulkhead and 2-hole flange connectors.
PCB Mount SMB connectors: These are soldered directly to PCBs with vertical or horizontal orientations. They are available in through-hole and edge-mount variants, making them suitable for compact electronic assemblies.

By Orientation

Straight SMB Connectors: They offer a direct, in-line connection, minimizing signal loss, signal path length, and reflection.
Right–Angle SMB Connectors: These are incredibly useful in applications with limited space.

By Impedance

50 Ohm SMB Connectors: The majority of SMB connectors are designed for 50 Ohm impedance, which is the standard for most general RF and microwave applications.
75 Ohm SMB Connectors: They are primarily utilized in video transmission and broadcast systems.

FAQ

 

 

Q: What is an SMB connector?

A: SMB (SubMiniature version B) connectors are compact RF connectors commonly used in applications where space is limited, such as in telecommunications, RF test equipment, and GPS receivers. They feature a snap-on coupling mechanism, offering quick and easy connections without the need for tools.

Q: What is the difference between SMA and SMB Connectors?

A: SMA and SMB connectors differ in size, frequency range, impedance, durability, and applications. SMA connectors are larger, handle higher frequencies, have two impedance options, and are used in telecommunications. SMB connectors are smaller, have a lower frequency range, primarily for 50 ohm impedance, and are used in consumer electronics.

Q: Can SMB Connectors of 50 ohms and 75 ohms be mixed?

A: 50 ohm smb connector and 75 ohm smb connector impedance should not be used interchangeably because their different impedance can cause signal distortion and performance decline. When selecting and using SMB connectors, please ensure they match the impedance requirements of the devices and circuits being used to ensure optimal signal transmission and connection quality.

Q: What is SMC vs SMB?

A: SMB and SMC can refer to different things, but they most commonly refer to types of RF coaxial connectors (SMB vs. SMC) or business types (Single-Member Company vs. Small and Medium Business). SMB/SMC coaxial connectors differ in their connection mechanism, with SMB being a "snap-on" type and SMC being a "screw-on" type. A single-member company (SMC) is a business structure owned by only one person.

Q: What is smaller than SMB connector?

A: Micro coaxial (MCX) connectors are small form-factor connectors. They are designed for use in applications with size or space limitations. Key advantages of MCX connectors include: Similar to SMB connectors but are 30% smaller.
