ERVAC SMA - 18 GHz Technical data Technical data SMA are precision models for microwave applications up to 18 GHz. . There is a huge variety of applica- tions for SMA types, as in telecom, test and measurement, instruments, avionics, etc. • Frequency range up to 18 GHz, extended frequency version up to 26.5 GHz • Excellent return loss • Intermateable with PC3.5 and PC2.92 • The SMA (Subminiature A) interface dimensions conform to the following standards: International: IEC 60169-15 Europe: CECC 22110 USA: MIL-C-39012 SMA - Interface MIL-STD 348a/310 28 min. max. min. max.
