Target Applications
Male-to-male format links a 1.85 mm precision connection to SMA-side bench hardware through 18 GHz.
The SMA male interface supports direct integration with SMA-connected fixture or cable-side connections in mixed test setups.
A 27.2 mm straight body and defined M7 / 1/4-36 UNS threads help control interface engagement and spacing.
VSWR ≤1.15 and 50 Ω impedance support low-reflection module measurements where 1.85 mm and SMA interfaces meet.
