SPnT Coaxial Subminiature Switches DC to 6 GHz, DC to 26.5 GHz, DC to 40 GHz
R591 RADIALL coaxial subminiature switches have a typical operating life exceeding 25 million cycles. Excellent RF & repeatability
characteristics along with a guaranteed life of 10 million cycles make these switches ideal for Automated Test Equipment (ATE) and
other measurement applications. These miniature switches are also an excellent choice for Mil/Aero applications due to their small
size, light weight, as well as outstanding shock and vibration handling capabilities.

The “QLF” tradermark (quick lock formula®) standard applies to QMA and QN series and guarantees the full
intermateability between suppliers using this tradermark.Using QLF certified connectors also guarantees the
specified level of RF performances.
Connector SMA2.9 is equivalent to “K Connector®”, registered trademark of Anritsu
Available with “solder pins “ models only
Polarity is not relevant to application for switches with TTL driver
Suppression diodes are already included with TTL option
