The series QWM manual waveguide switches from QuinStar Technology are available in seven waveguide bands operating from 18 to 110 GHz. These waveguide switches are manual 4-port devices and have a 3-channel rotor accurately indexed to eight 45 degree positions that allows each port to be connected or isolated from any other port. These switches are precision machined with bearing and indexing grooves for smooth operation and accurate positioning. They are useful in test set ups and system applications where transfer switching is required. In addition to standard manual switches, custom electromechanical waveguide switches are also available.
