SSMB PCB Mount RF Connectors are sub-miniature coaxial interconnects designed for direct mounting onto printed circuit boards in high-density RF and microwave assemblies. As a smaller variant within the SSMB (Sub-Sub-Miniature B) series, these connectors use a snap-on coupling mechanism that allows fast mating and unmating without threading, which is beneficial in space-constrained board layouts such as antenna modules, GPS modules, wireless communication cards and test equipment interfaces. SSMB PCB Mount RF Connectors typically operate up to several GHz and maintain stable impedance matching (50 ohm or 75 ohm depending on configuration), supporting consistent signal transmission with low insertion loss and low VSWR across the rated frequency range.
Yangzhou Jingcheng Electronics Co., Ltd (JC Company) manufactures SSMB PCB Mount RF Connectors along with a broad range of RF coaxial interconnection products, applying CNC machining and network analyzer testing during production to control dimensional accuracy and electrical performance. Materials commonly used in SSMB PCB Mount RF Connectors include brass or beryllium copper shells with gold, silver or nickel plating, combined with PTFE insulators to support signal integrity and mechanical durability over repeated mating cycles.

Application Scenarios
SSMB PCB Mount RF Connectors are applied in GPS and GNSS modules, wireless communication boards, small antenna assemblies, IoT devices, automotive electronics and test/measurement instruments where board space is limited and quick-connect functionality is required. Their compact size allows integration into densely populated circuit boards without significantly increasing footprint, while the snap-on coupling reduces mating time compared with threaded connector types.
Selection Points
- Frequency range and impedance requirement of the RF signal path
- Mounting orientation needed on the PCB (straight, right angle, or panel mount)
- Plating material (gold, silver, nickel) based on environmental and conductivity requirements
- Mating cycle durability required for the application
- Board space and connector footprint constraints
- Compatibility with mating cable assembly or connector type
FAQ
Q: What frequency range do SSMB PCB Mount RF Connectors support?
A: SSMB PCB Mount RF Connectors generally support operation up to several GHz, with exact frequency range depending on the specific design and dielectric material used.
Q: What is the difference between SSMB and SMB connectors?
A: SSMB connectors are smaller than SMB connectors while both use snap-on coupling; SSMB is generally selected when board space is more limited.
Q: Can SSMB PCB Mount RF Connectors be customized?
A: Yes, dimensions, plating and mounting configuration of SSMB PCB Mount RF Connectors can be adjusted according to application requirements. Yangzhou Jingcheng Electronics Co., Ltd supports customized specifications in addition to standard product offerings.
Q: What testing is performed on SSMB PCB Mount RF Connectors before shipment?
A: Electrical parameters such as insertion loss and VSWR are typically verified using network analyzer equipment to confirm consistency with design specifications.
