SMP Connectors

Amphenol RF SMP Connectors feature a subminiature interface in the same scale as MMCX connectors while offering a frequency range of DC to 40GHz. These SMP connectors are commonly used in miniaturized high-frequency coaxial modules and are offered in both push-on and snap-on mating styles. The interface is ideal for PC board-to-board interconnect and utilizes 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 0.020" of radial float and 0.010" of the axial float. One male connector is typically specified as a snap-on interface and the other as a push-on. This ensures the bullet adapter remains fixed in the same male connector if the PC boards are separated. Amphenol RF SMP connectors feature bullets in multiple lengths for different board spacing.
