SMP

The SMP interface is a subminiature interface in the same scale as MMCX connectors but offers a frequency range of DC to 40 GHz. It is commonly used in miniaturized high frequency coaxial modules and is offered in both push-on and snap-on mating styles.

The interface is an excellent choice for PC board to board interconnects. For these applications, the interface series offers an interesting solution by utilizing a male connector on each of the PC boards and a female-to-female adapter mounted in between to complete the connection.

In its snap-on configuration, the SMP interface is available in two levels of detent each with different mate and de-mate forces. The two levels are full detent and limited detent. In board mount applications, the lower level of detent (limited detent) is typically selected, as it is only required to retain the bullet. Full detent is often used for discreet cable connections where higher forces are desirable.
