SMB Connectors

SMB Connectors – Compact Snap-On RF Coaxial Connectors for Space-Constrained Applications

SMB connectors deliver compact RF performance with fast push-on mating. As a result, they work well in applications where space is limited and installation speed matters. Compared with threaded RF interfaces such as SMA connectors, SMB connectors provide a smaller footprint and a quicker connection method. For this reason, engineers use SMB connectors in RF cable assemblies, PCB-mounted designs, instrumentation systems, and compact communication equipment.

HUADA GROUP supplies a wide range of SMB connectors. For example, you can choose SMB male connectors, SMB female connectors, SMB cable connectors, right angle SMB connectors, PCB mount SMB connectors, bulkhead SMB connectors, and SMB connector adapters. In addition, our 50 ohm and 75 ohm SMB solutions support different cable types, mounting styles, and RF system requirements.

Whether you are developing a new RF design or replacing an existing component, our SMB connector series provides practical and flexible options for modern electronic systems.

Why Choose SMB Connectors?

Our range combines compact size, fast installation, and stable RF performance.

Compact Design for Limited Space

These connectors reduce mechanical footprint. Therefore, engineers use them in compact RF modules, PCB layouts, and space-constrained enclosures. In many cases, they replace larger RF interfaces to improve layout efficiency.

Fast Push-On Mating

The snap-on design eliminates threaded coupling. As a result, users can connect and disconnect quickly without tools. Furthermore, this feature improves efficiency in test environments and modular RF systems.

Flexible Configuration Options

Multiple mechanical structures are supported. For example, you can select:

• Straight versions
• Right angle versions
• PCB mount styles
• Bulkhead styles
• Cable assembly types
• Adapter configurations

In addition, these options help engineers adapt the interface to different mechanical layouts.

Multiple Impedance Options

Two main impedance types are available:

-50 Ohm
50 ohm versions are suitable for RF and wireless systems, including antennas, GPS modules, and communication devices.

-75 Ohm
75 ohm versions can be used in broadcast, video, and digital signal applications. In many cases, they support stable signal transmission in media systems.

Our SMB Connector Types

SMB Male Connector (SMB Plug)

The SMB male connector uses a center pin and works as the plug side of the interface. Engineers typically use it in cable assemblies and adapter configurations.

Common versions include:

• Straight SMB male connectors
• Right angle SMB male connectors
• Cable termination types
• Adapter-style configurations

SMB Female Connector (SMB Jack)

The SMB female connector uses a socket contact and serves as the jack side of the interface. Engineers usually install it on PCB boards, panels, and RF equipment. In many designs, SMB female connectors therefore act as fixed connection points for modular RF systems.

SMB Cable Connector

SMB cable connectors terminate coaxial cables and provide stable RF transmission. For example, they support flexible cables such as RG-174, RG-316, and RG-58, depending on system requirements. In addition, some SMB cable connector series also support semi-rigid cable assemblies for higher mechanical stability.

Right Angle SMB Connector

Right angle SMB connectors change the cable direction by 90 degrees. Therefore, engineers use them in compact layouts where straight connectors cannot fit. Consequently, this design reduces cable stress and improves routing inside dense electronic systems.

SMB PCB Mount Connector

SMB PCB mount connectors connect RF signals directly to printed circuit boards. Engineers use them in RF modules, test equipment, and communication devices.

Common PCB styles include:

• Through-hole PCB mount
• Surface mount designs
• End-launch configurations
• 90-degree PCB mount options

SMB Bulkhead Connector

SMB bulkhead connectors provide a secure panel feed-through connection. Engineers install them on enclosure walls to separate internal and external RF paths. In many applications, bulkhead designs thus improve mechanical stability and system organization.

SMB Connector Adapters

SMB connector adapters connect SMB interfaces with other RF standards. For example:

• SMA to SMB connector
• SMB to SMA connector
• SMB to BNC connector
• SMB to F connector adapter

As a result, you can integrate SMB connectors into mixed-interface systems without redesigning the entire RF chain.

SMB Connector Applications

SMB connectors support a wide range of RF and electronic systems.

Telecommunications Systems

Engineers use SMB connectors in RF modules, signal paths, and communication equipment. In many cases, SMB connectors improve compact system integration.

Automotive Electronics

SMB connectors support GPS systems, telematics modules, and in-vehicle RF communication. In automotive designs, moreover, compact size and vibration stability are important factors.

Test and Measurement Equipment

SMB connectors are widely used in RF test setups. For example, engineers use them in signal generators, analyzers, and laboratory instruments.

Broadcast and Digital Systems

75 ohm SMB connectors support video transmission, DAB systems, and digital audio applications. Therefore, they are common in media and broadcast environments.

Medical and Industrial Equipment

SMB connectors also appear in diagnostic devices and industrial control systems. In these applications, both compact size and stable RF performance are key requirements.

How to Select the Right SMB Connector

To select the correct SMB connector, consider the following factors:

1. Impedance
First, choose 50 ohm or 75 ohm based on your RF system requirements.

2. Connector Gender
Then confirm the interface type:

• SMB male connector (plug)
• SMB female connector (jack)

3. Cable Type
Next, match the connector with your coaxial cable, such as RG-174, RG-316, or semi-rigid cables.

4. Mounting Method
After that, select the installation style:

• PCB mount
• Cable mount
• Bulkhead mount
• Right angle configuration

5. Electrical Requirements
Finally, review frequency range, insertion loss, VSWR, and mechanical durability before final selection.
