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. The female adapter is often called a bullet and is necessary to provide
a flexible link between the male connectors. This flexible link allows .020 inches of radial float and .010 inches of
axial float. Typically, one male connector will be specified as a snap on interface and the other as a push on. This
ensures that the bullet adapter remains fixed in the same male connector if the PC boards are separated. The bullets are
available in multiple lengths to allow for different board spacing.
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.
