Sub miniature push-on (snap-on) connector, operating in the range DC-40 GHz

50 ohms / part series R222 (AEP 75XX)

SMP connectors were introduced in the 2000s for high frequency blind mate applications and is standardized according to MIL-STD-348A fig. 326. A cost effective version SMP-COM (part series R222 9) is also available for telecom applications up to 12 GHz.

Performance :

  • Impedance : 50Ω
  • Frequency range : DC ~ 40 GHz (SMP-COM : DC ~ 12.4 GHz)
  • Durability :
    • Full detent : 100 mating cycles
    • Limited detent : 500 mating cycles
    • Full detent : 1 000 mating cycles
  • Power rating at 1 GHz : 100W
  • Temperature range : -65°C / +165°C
  • Radial misalignment : +/-0.25mm
  • Axial misalignment : 0/+0.25mm (with fixed length adapters)
  • The use of spring loaded adapters enables larger axial tolerance.


  • The outer diameter of the interface is approx 3.30mm

Specific for non magnetic P/Ns:

  • Products are guaranteed that relative distortion of a magnetic field of 1.5T, generated by a non-magnetic connector, is less than 5 * 10-7 (0,5 ppm) at a distance of 10 mm from the surface of the connector
