QMA
Product code FDCTNL
Based on the SMA connector standard, Rosenberger QMA connectors are designed for applications up to 18 GHz. The quick-lock mechanism enables easy and reliable connections in the tightest of spaces – primarily in mobile base stations – and 10 times faster compared to SMA offerings. Packing density is also superior to SMA due to the minimum pitch and toolless connection, dispensing with the need for torque spanners for fastening coupling nuts. Rosenberger offers QMA as standard version and with plastic quick-lock mechanisms in four different color codings. QMA is not intermateable with SMA.

Specification Sheet
Rosenberger provides a wide range of compact calibration kits in various series for MSOT (4-in-1) and MSO (3-in-1) calibrations. Compact calibration kits combine all necessary calibration standards in one unit and can be applied for MSO calibrations (3-in-1, open, short, load) of single port vector network analyzers and MSOT calibrations (4-in-1, open, short, load, thru) of 2- or more-port vector network analyzers. All compact calibration kits come in a hardshell case with a lanyard and with general coefficients on a standard definition card.
