The present application describes a connector assembly, a circuit board assembly, a cable assembly and to a method of manufacturing a connector assembly. A connector assembly comprises a shroud; and a plurality of co-axial radio frequency connectors at least partially received in the shroud such that the shroud extends around each radio frequency connector and between adjacent radio frequency connectors. The shroud comprises at least one piece of radiowave absorption material arranged to absorb radio frequency energy leaking or dispersing from the radio frequency connectors in use. Another connector assembly comprises a body, a plurality of radio frequency connectors at least partially received in the body, and a conductive foil integrally formed with the body and partially extending beyond the body.
