Amphenol RF offers a full range of SMPM board-to-board configurations. In a typical board-stacking configuration, a full detent PCB jack and a smooth bore PCB jack are mounted to the top and bottom boards. A bullet adapter is inserted into and held securely by the full detent jack, and the smooth bore PCB jack accepts the opposite end of the bullet adapter. Currently, three bullet adapters are available allowing stack heights from 6.65 mm to 9.7 mm.
