Rosenberger Mini-SMP connectors are extremely small coaxial connectors, approximately 70% of standard SMP size. They are designed for applications up to 65 GHz and mainly for high-speed signal transmission (typically 10 or 40 Gbps). Plugs are available as smooth bore-versions – for plug-in technology and backplane applications – and as vibration resistant full detent types, for the highest mechanical loads such as those found in aerospace engineering.

Mini-SMP subminiature connectors are well-proven, offering a high level of flexibility in alignment tolerances and for simplifying the whole production process. Rosenberger Mini-SMP coaxial connectors are mateable with common Mini-SMP connectors as specified by MIL-STD-348A, Fig. 328, as well as GPPO (Gilbert Engineering Co., Inc.) and SSMP (Carlisle Interconnect Technologies) series. 

The PCB connectors are supplied in tape and reel packaging for automatic assembly to boards and also in blisters.
