Because of its unique setup, this connector features no electrical length or phase variation under any type of movement (shock, vibration, etc.), It hass when compared to a standard SMA connector. eduction is concerned. -348, and a mated SMPM-T connector is 75% and 80% less thas the smallest threaded interface possible for compliance with MIL-STD-348. A mated SMPM-T connector has a 75% and 80% reduction in mass when compared to a standard SMA connector. The SMPM-T is ideal for numerous applications – it meets the hi-rel materials requirements of NASA while offering full compliance with RoHS and REACH legislation for commercial needs.
