Specifications
SSMA Male Connector
SSMA Family
SSMA (SubMiniature A) is a scaled-down version of the standard SMA connector, offering SMA-compatible electrical performance in a smaller footprint for use at frequencies up to 40 GHz. It is used in high-frequency test equipment, millimeter-wave modules, and dense PCB assemblies where standard SMA connectors would take up too much board space.
Typical Applications
RF cable assemblies, antenna connections, test equipment patching, and field installations.
Gender & Polarity Note
This is a Male connector — it has a center pin that inserts into a female socket. Male connectors are used on cable assemblies and pigtails that plug into equipment jacks.
Frequently Asked Questions
What frequency range does the SSMA Male connector support?
SSMA connectors are rated DC – 38 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 SSMA connector be mated and unmated?
SSMA Male 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 SSMA connector?
SMA connectors should be tightened to 3–5 in-lb (0.34–0.56 N·m) using a torque wrench. Over-tightening can damage the mating threads and distort the center contact.
Are the SSMA 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 SSMA Male connectors ship assembled and tested?
Yes. Every cable assembly — including those terminated with SSMA Male connectors — is hand-assembled and continuity tested before shipping. Cables ship free within the US from our US facility.
