What is a SMB RF Connector?
Summary
Our SMB (Subminiature Type B) RF connectors feature a 50 Ω impedance and snap-on coupling. They are commonly used in internal devices, PCBs, and board-to-board mounting. These connectors deliver reliable performance up to 4 GHz and ensure quick, dependable connections for high-density applications.
SMB RF Connectors by Type
Micro-Coaxial Cables
Trivia: About Cables
- MIL Standard Cables
These cables, also known as Mil-Spec, are engineered to meet rigorous US military specifications for performance and durability. They often feature the "RG" prefix, which stands for "Radio Guide," reflecting their roots in radio technology. They are critical in demanding applications like defense, aerospace, and telecommunications, where reliability is non-negotiable.
- Micro Coaxial Cables
These ultra-thin cables are designed to connect to miniature RF connectors like U.FL. They ensure signal integrity in space-constrained devices such as smartphones, laptops, and medical equipment, making them vital for modern compact electronics.
SMB RF Connector Features
Compact Size
Even smaller than SMA connectors, SMB connectors allow high-density wiring and mounting between subassemblies and devices within limited spaces.
Easy Connector Coupling
The snap-on method enables easier coupling than threaded methods, allowing quick connector attachment ideal for tight spaces.
High-Frequency
Our product lineup supports high-frequency applications from DC up to 4 GHz.
SMB RF Connector Applications
Due to their compact size and snap-on coupling, SMB RF connectors are designed for small communication devices. They excel in space-constrained setups and are ideal for internal devices, PCBs, and board-to-board mounting. Operating up to 4GHz, they suit high-frequency needs in compact systems. Their snap-on design ensures quick, reliable connections, making them perfect for high-density applications like handheld radios, GPS units, and medical equipment.

SMB Type RF Connector FAQ
QWhat is the difference between SMA and SMB connectors?
QWhat is the difference between SMA and SMB connectors?
SMB connectors are slightly smaller than SMA connectors (Subminiature Type-A). SMA's threaded coupling resists vibration better and disconnects less easily. SMB's snap-on coupling is easier, requires less effort, and works better in tight spaces. MCX and MMCX connectors are also small connectors using snap-on coupling.

QWhy does the contact shape differ from other connectors?
QWhy does the contact shape differ from other connectors?
Usually, plugs have male contacts, and jacks have female contacts, mating when connected. SMB connectors reverse this arrangement—plugs have female contacts, and jacks have male contacts. Reverse-polarity SMA connectors also use reversed contacts.
