KH-SMBK-SMBK-RG1.37-100MM Compact SMB RF Cable Assembly for Space-Constrained Applications

The Kinghelm KH-SMBK-SMBK-RG1.37-100MM is a finished SMB RF cable assembly, pre-assembled with SMB female connectors on both ends and a 100 mm RG1.37 coaxial cable in between. It is supplied as a ready-to-use cable assembly, eliminating the need for customers to perform connector crimping, cable cutting, or cable assembly on site.

Designed for short-distance RF signal connections, this finished cable assembly combines two straight gold-plated SMB female connectors, RG1.37 black coaxial cable, and protective sleeves into one complete product. With its compact 1.37 mm cable diameter and 100 mm finished length, it is suitable for internal connections between RF modules, PCBs, communication equipment, test equipment, and other compact electronic devices.

Ready-to-Use Finished Cable Assembly

Unlike loose RF connectors or bulk coaxial cable, the KH-SMBK-SMBK-RG1.37-100MM is supplied as a complete finished cable assembly. The connectors have already been assembled onto the RG1.37 coaxial cable according to the specified cable length.

This finished design saves users the additional work of cable cutting, stripping, connector termination, and assembly. For equipment manufacturers, engineers, and production teams, using pre-assembled RF cable assemblies can simplify the wiring process and improve installation efficiency.

The 100 mm finished length also provides a convenient solution for connecting RF interfaces located close to each other without requiring users to process the cable themselves.

SMB Female-to-Female Configuration

Both ends of the finished cable are equipped with straight SMB female connectors with gold-plated contacts. The two identical connectors form an SMB-K to SMB-K connection configuration.

This design is suitable for connecting compatible SMB male interfaces in RF modules, circuit boards, communication equipment, and testing systems. Because the connectors are already installed, the cable can be directly used after delivery, making it convenient for equipment assembly and maintenance.

Compact RG1.37 Coaxial Cable

The cable assembly uses RG1.37 black coaxial cable with an outer diameter of approximately 1.37 mm. Its slim profile is particularly suitable for compact electronic equipment where internal installation space is limited.

The 1.37 mm cable diameter allows the finished assembly to be routed flexibly around components and PCB layouts. Combined with the 100 mm finished length, it is well suited for short-distance internal RF connections.

Suitable for Equipment Assembly and RF Applications

As a ready-made RF cable assembly, the KH-SMBK-SMBK-RG1.37-100MM can be used in various applications, including:

• RF module-to-module connections
• PCB and RF module connections
• Internal wiring of communication equipment
• Wireless communication devices
• RF testing equipment
• Laboratory test setups
• Compact electronic equipment
• Short-distance RF signal connections

For manufacturers purchasing RF cable assemblies in volume, a finished and standardized cable can also help simplify production processes and reduce the need for in-house cable termination.
