SSMA Connectors
High-frequency, compact RF connectors designed for demanding precision applications
Overview
Amphenol RF’s SSMA connectors are compact, subminiature solutions developed to meet the growing demand for higher frequency, precision RF performance in space-constrained applications. These 50 ohm connectors are ideal for use in systems where SMA connectors are too large, offering similar mechanical designs in a smaller form factor.
Engineered for DC to 40 GHz performance, SSMA connectors feature a screw-on coupling mechanism that ensures consistent electrical performance and mechanical stability even in challenging environments. Their robust design makes them suitable for test and measurement, instrumentation, military and aerospace systems.
