QuinStar Technology’s series QWM waveguide switches are manual 4-port devices. They 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. The switches are available in seven waveguide bands covering the frequency range of 18-110 GHz and 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.
