FAQs
What are SMA connectors used for?
SMA connectors are utilized in coaxial cable assemblies, coaxial cable installations, coaxial cable repair, and premise wiring applications. These subminiature version A connectors serve electronics, medical, industrial automation, military, and telecommunications industries where reliable RF connections are essential for high-frequency coaxial transmission up to 12.4 GHz.
What is the difference between standard and reverse polarity SMA connectors?
SMA connectors are offered in both standard and reverse polarity versions. While both maintain 50-ohm impedance and support frequencies up to 6 GHz, 11 GHz, and 12.4 GHz, reverse polarity configurations provide alternative connection options for specific applications. Both versions are available in male, female, plug, and jack configurations with maximum VSWR of 1.3 to 1.5.
How do I choose between crimp and solder SMA connectors?
SMA connections come with solder, crimp, or crimp/solder attachment methods. The selection depends on your specific coaxial cable assembly, installation, or repair requirements. L-com offers SMA connectors in all three attachment configurations to accommodate different termination needs for premise wiring and coaxial cable applications.
What coaxial cable types are compatible with SMA connectors?
L-com's SMA cable connectors are compatible with a wide range of coaxial cable types, including RG58, RG316, RG174, RG188, RG141, RG142, RG8, LMR-200, LMR-400, CA-100, CA-200, CA-240, CA-400, CA-195, CA-195R, CA-195RW, WBC100, WBC195, WBC200, WBC240, WBC400, 100-Series, 195-Series, 240-Series, 400-Series, CNT-195, TWS-195, Belden 7805, Belden 7807, Belden 7808, Belden 7810, Belden 8240, Belden 8219, and Belden 9913.
What frequency range do SMA connectors support?
SMA RF connectors feature 50-ohm impedance and support frequencies up to 6 GHz, 11 GHz, and 12.4 GHz depending on the connector series. With maximum VSWR specifications of 1.3 to 1.5, these connectors are ideal for high-frequency coaxial transmission applications across electronics and telecommunications installations.
What materials are SMA connectors made from?
SMA connectors are available with nickel-plated or gold-plated brass bodies for durability and corrosion resistance. Insulation materials include PTFE and TFE, providing durability and weather resistance. Physical dimensions range from 0.41 to 1.22 inches, and connectors are available in straight and right-angle body designs with bulkhead mounting and flange-mount options.
