The W1 Connector launcher family includes both Male and Female (W1-105F) screw-in type connectors. The W1 Connector has an air-dielectric front-side interface similar to K and V Connectors. The center conductor is supported by Anritsu’s Proprietary low-loss Plastic Bead on one end and by a Teflon bead on the other end to provide exceptional concentricity and rigidity to the pin on its backside. The center conductor extends outside of the connector and allows the user to make a direct-pin overlap connection to the Microwave Circuit. The threads on the backside of the W1 Connector allow the user to install a W1 Connector by screwing it into the housing wall.
