SMP & SMPM RF Blind-Mate Connectors Molex SMP and SMPM RF Connectors deliver high density and excellent frequency performance. SMP subminiature connectors have a DC to 40GHz frequency range and offer space-saving vertical mating and push-on or snap coupling. SMP is ideal for a wide range of applications from wireless to military. SMPM connectors are 30% smaller than SMP designs and are ideal for compact applications requiring a high level of optical density. SMPM has a DC to 65GHz frequency range.
