High-frequency SMA adapter improves VSWR performance

11-11-2021 | Amphenol | Subs & Systems

Amphenol RF has expanded its robust adapter portfolio with a high-performance right-angle SMA adapter. This adapter is intended to provide improved VSWR over a right-angle soldered design with a similar footprint without utilising an expensive swept body style. The right-angle SMA adapter is excellent for SATCOM, radar and test and measurement applications.

Traditional right-angle connectors are frequently connected with poor VSWR performance, especially at frequencies approaching the limit of the connector. This is due to the typical use of a two-part internal straight contact. While the straight configuration provides for simple assembly and low cost, its shape is not advantageous for internal impedance control or lend itself to a sturdy solder connection. This high-frequency right-angle SMA adapter alternatively employs a two-piece concept with an internal swept right-angle configuration. This includes all the physical advantages of standard right-angle designs (low profile, compact size, etc.) while maintaining electrical performance comparable with conventional straight connectors.

The high-performance right-angle SMA adapter features a gold-plated brass body and gold plated, beryllium copper contact. This 50-Ohm adapter operates up to an extended frequency range of DC to 22GHz. This adapter can be employed along with their line of ATC-PS precision test cables offered in several pre-configured lengths.
