140 – 220 GHz, Four Position Manual Waveguide Switch

530G/387, Insertion Loss 1.0 dB, VSWR 1.25:1, Isolation 45 dB


Mi-Wave’s 530 Series waveguide switches consists of a waveguide switch selection and a rotary motor encased in a machined housing. They are particularly useful in operational systems and test setups where they supply variety of switching combinations.

Each unit will operate over the full waveguide bandwidth with minimum insertion loss, minimum VSWR, and maximum isolation between coupled and uncoupled waveguide sections.

Manual Waveguide Switch

The 530 Series Manual Waveguide Switches are used for transmission switching applications in millimeter wave systems. These versatile devices provide a variety of switching combinations using three waveguide channels and three positions. In a typical radar application, a three-position switch can be used manually to switch one of two transmitters to a common antenna, while simultaneously connecting the other transmitter to a suitable termination. A manual switch will also provide a convenient means for alternately connecting a test antenna and standard horn to gain-measuring test equipment.

Other frequency bands and custom configurations available.
