Field-Replaceable SMAs Cut Loss From DC To 26.5 GHz

Sept. 16, 2008

A LINE OF RUGGED, field-replaceable 50-ohm SMA connectors features low insertion loss through DC to 26.5 GHz, with usable performance through 31 GHz. The connectors feature passivated 303 stainless-steel bodies with gold-plated center contacts and PTFE insulators for superior voltage-handling capabilities. They exhibit VSWR of 1.07:1 or better from DC to 11 GHz, 1.25:1 or better through 20 GHz, and 1.38:1 or better through 26.5 GHz. The rugged coaxial connectors meet the mechanical interface requirements of MILSTD- 348 for military and aerospace applications. The field-replaceable SMAs are available in versions with integral EMI gaskets and for groundplane mounting (without EMI gaskets). They are designed for operating temperatures from -65 to +165C. Connectors include models for mating with 0.012-, 0.015-, 0.018-, and 0.020-in. center pins.
