75Ω RF Connectors Product Roundup

This week’s Product Roundup highlights 75Ω RF connectors and cable assemblies from leading suppliers, as well as corresponding tooling.

75Ω RF Connectors

75Ω RF connectors from RadiallRadiall offers large range of true 75Ω connector interfaces designed to support frequencies up to 6GHz and to match the characteristic impedance of 75Ω coaxial cables used for their low attenuation and low distortion characteristics. The range includes BNC 75, MCX 75, AEP 75, N 75, and TNC 75 Series connectors and is ideally suited for use in telecom and broadcast applications but can be used wherever a video transmission is required, including in aerospace, defense, industrial, rail, medical, space, and test and measurement applications. Radiall’s BNC 75 Series connectors, for instance, are available in standard versions designed to support DC to 1.5GHz performance for a minimum of 500 mating cycles and BNC 75 HDTV versions designed to support DC to 6GHz performance as well as higher data rates up to 3Gb/s for a minimum of 1,000 mating cycles. Both have an outer interface diameter of approximately 9.70mm and are rated for 1,000W at 1GHz and for operating temperatures extending from -65°C to +165°C.

75Ω RF connectors from SamtecSamtec’s new 75Ω BNC solution has an exclusive, low-profile, right-angle design that’s optimized for high-volume manufacturing and exceeds 12G-SDI performance requirements for broadcast video systems. The new 75Ω, right-angle BNC (BNC7T-BM Series) features mixed surface-mount and through-hole (SMT/TH) technology, is designed for use on 1.60mm PCBs, and has a height profile of 10.15mm (0.400”), adequate surface area for pick-and-place vacuum sealing, and balanced mass distribution to support the use of pick-and-place machinery during assembly without fixturing. Performance passes 12G-SDI, SMPTE ST-2082-1 requirements by better than 10dB out to 12GHz and a complete characterization report is available in the Test Reports tab located here. The Samtec RF Technical Group provides custom launch design services for optimizing performance of 12G-SDI interconnects into a system, as well as product design, modeling, simulation, and measurement services.

The MCX connectors offer 30% space savings over similar SMB and SMC types and are also available in a 12G-SDI design. The MMCX connectors are 30% smaller than MCX variants, are available with cable or PCB terminations, and are especially ideal for Wi-Fi, IoT, and M2M communications applications. The SMA connectors are available in both waterproof and 26.5GHz designs. The TNC connectors can be used in the same applications as BNC connectors but have a threaded design that’s more robust than BNC types and are also available in waterproof designs. The Ultra-Tiny BNC connectors are 51% smaller than standard BNCs, offer waterproof designs, and are especially well suited for use in broadcasting applications. The 12G-SDI BNC connectors are also available in waterproof designs and are identical to standard 75Ω BNC connectors but designed for 12G-SDI broadcasting applications. The 6G-SDI 1.0/2.3 connectors have a miniature size that provides a more flexible mechanical solution for space-constrained broadcasting applications and are identical to standard 75Ω 1.0/2.3 connectors.

75Ω RF connectors from SmithsSmiths Interconnect’s standard coaxial contacts provide flexibility in the design of high-frequency RF and microwave applications including communications, instrumentation, and radar equipment. Designed for low-loss, concentric, 50Ω and 75Ω cable types, the contacts are available in sizes 5, 8, 9, 12, and 16 and have the same outline dimensions as traditional power contacts to ensure compatibility with a variety of standard and high-density insert arrangements — including MIL-DTL-38999, ARINC 404, ARINC 600, and SAE-AS39029 arrangements — in D-Sub, circular, and rack and panel connectors. The line’s 50Ω contacts are compatible with flexible RG-178 and RG-316 cables and semi-rigid SR.047 and SR.080 cables; its 75Ω contacts are compatible with flexible cables such as RG-179; and both exhibit a maximum VSWR rating of 1.3:1 from DC to 5GHz.
