SMA 27.0 GHz High Performance Inquire

These high-performance SMA connectors feature maximum VSWR of 1.10:1 from DC to 18 to 27.0 GHz. They are designed to provide enhanced durability and reliability in a "field grade" production connector.

The internal design is optimized using state-of-the-art Electromagnetic Finite Element Analysis model simulation to provide low reflection coefficient, with mode free operation to 27.0 GHz.

In addition, this connector series provides -100 dB RF leakage due to the precision finish on the interface and mounting surfaces to assure a solid 360-degree contact in the critical RF return path, and the absence of epoxy holes in the connector body. The design of the internal structure provides a reliable and mal disturbance axial captivation by mechanical means with a minimal disturbance to the transmission line characteristics and has a maximum continuous service temperature of 165 degrees C.

SMA 27.0 GHz field replaceable connectors are available in 6 common mounting flange configurations. Both the field replaceable and thread-in (spark plug) connectors are available for use with hermetic seals or accessory pins with diameters of .009, .012, .015, .018, .020, and .036 inches. Standard hermetic seals are also shown in the brochure, and can be modified to a wide range of configurations to match application requirements.

These connectors are machined to exacting tolerances and the highest quality standards on the modern CNC turning centers, and assembly is tightly controlled and monitored to ensure peak consistency of performance from unit to unit.
