Similar performance is achieved with the complete MA2-Line N, TNC and SMA connectors and adapters using a Teflon dielectric.Ī completely different approach is needed to achieve such good performance for the SA2-Line connector series using air as the dielectric and a bead for captivation. up to 18 GHz, and the typical performance being even better. The improvement of the electrical performance is measurable, with the adapter, a TNC male to TNC female, shown in Figure 3, having a VSWR of 1.15 max. As for the center conductor and the dielectric, special machining and assembly techniques are used, employing machined parts with similarly tight tolerances as those applied to the outer conductor. In fact, tolerances in the important areas at the outer conductor internally are ±5 µm (☒/10,000 inches).

All of these methods were evaluated when Spectrum Elektrotechnik developed its SA2-Line (Smooth Angle Air) swept angled adapters and connectors and MA2-Line (Mitered Angle Air) adapters and connectors.Īlso, as parts are not joined mechanically, very tight tolerances can be set. Basically, angled connectors have to be made from joining straight pieces together, or the straight components have to be formed into the angled configuration, or a casting has to be manufactured, which usually cannot be achieved within tight tolerances. It is almost impossible to completely control the solder flow or to compensate for excessive solder.Īs can be seen, making straight connectors with tight tolerances is not easy, so making parts that go around corners is even more complicated. The soldering process also has to be taken into consideration. Although captivation adds necessary ruggedness, it also causes electrical disturbance that has to be compensated for. Captivation techniques are epoxy, shoulder, single barb and double barb. Cable Assemblies with Interchangeable ConnectorsĪlso, the captivation of the center conductor with the outer conductor isolates the axial and rotational forces associated with the coupling of connectors from the elements to which the center conductor is attached and maintains the specified dimensions at both ends of the connector or adapter.

Cable Assemblies with Multipin Connectors.

High Performance Flexible Cable Assemblies.

This adapter can be used along with our line of ATC-PS precision test cables which are available in a number of pre-configured lengths. This 50 ohm adapter operates up to an extended frequency range of DC to 22 GHz. The high-performance right-angle SMA adapter features a gold plated, brass body and gold plated, beryllium copper contact. This incorporates all of the physical advantages of standard right-angle designs (low profile, compact size, etc.) while maintaining electrical performance comparable with conventional straight connectors. The recently released high-frequency right-angle SMA adapter instead uses a two-piece concept with an internal swept right-angle configuration. While the straight configuration allows for easy assembly and low cost, it’s shape is not advantageous for internal impedance control or lend itself to a robust solder connection. This is due to the typical usage of a two-part internal straight contact. Traditional right-angle connectors are often associated with poor VSWR performance, particularly at frequencies approaching the limit of the connector. The right-angle SMA adapter is ideal for SATCOM, radar and test and measurement applications.

This adapter is designed to offer improved VSWR over a right-angle soldered design with a similar footprint, without using an expensive swept body style. Amphenol RF has expanded its robust adapter portfolio with a high-performance right-angle SMA adapter.
