Specifications
SMB FEMALE ANGLE Connector
SMB Family
SMB (SubMiniature version B) is a snap-on RF connector with a simple push-on coupling rated to 4 GHz. Its ease of mating and small footprint make it popular in telecommunications equipment, set-top boxes, GPS timing receivers, and instrumentation where a secure but easily disconnected interface is needed.
Typical Applications
Telecom equipment, set-top boxes, GPS timing receivers, instrumentation, internal PCB-to-cable connections.
Gender & Polarity Note
Check the product datasheet for gender and polarity details. RF connectors are available in male (pin), female (socket), and reverse-polarity (RP) variants.

Frequently Asked Questions
What frequency range does the SMB FEMALE ANGLE connector support?
SMB connectors are rated DC – 4 GHz. The effective upper frequency of a cable assembly is limited by the lowest-rated component — either the cable or the connector. Always verify both are within spec for your target frequency.
How many times can a SMB connector be mated and unmated?
SMB FEMALE ANGLE connectors are rated for approximately 500 mating cycles. Exceeding this can cause wear on the contact surfaces, increasing insertion loss and VSWR. For applications with very frequent connects and disconnects, consider a connector rated for higher cycle counts.
What torque should I use to tighten a SMB connector?
Use a torque wrench and follow the connector manufacturer's recommended torque specification. Hand-tight plus a quarter turn is a safe starting point for most push-on connectors.
Are the SMB connectors on CoaxRF assemblies weatherproof?
Our standard cable assemblies use high-quality connectors suitable for most indoor and sheltered outdoor applications. For fully weatherproof outdoor installations, we recommend applying self-amalgamating tape over the connector junction to prevent moisture ingress.
Do CoaxRF cables with SMB FEMALE ANGLE connectors ship assembled and tested?
Yes. Every cable assembly — including those terminated with SMB FEMALE ANGLE connectors — is hand-assembled and continuity tested before shipping. Cables ship free within the US from our US facility.
