Target Applications
Converts a 1.85 mm female test interface to SMA male for measurement paths operating through 18 GHz.
The mixed-interface format connects SMA-based bench cabling with equipment or fixtures using a 1.85 mm interface.
A 28.05 mm straight body and defined M7 / 1/4-36 UNS threads support compact mixed-interface fixture layouts.
VSWR ≤ 1.15 and 50 Ω impedance support module measurements that require both 1.85 mm and SMA connectivity.
