The 33 series of precision W1 Adapters enable accurate measurements with Anritsu W1 Connector (1.0 mm Connector) at broad frequency range of up to 110 GHz. The 33 series W1-W1 Adapters are also available in two other connector sex configurations of M-M (33WW50), and F-F (33WFWF50). W1 Adapters have an air dielectric interface and a center conductor that is supported by a low loss PPO plastic bead. When used as connector savers with Test Ports in Test Systems, these adapters protect the Test Port by reducing the number of connections.
