Features of  Mi-Wave Polarization Switches

Mi-Wave’s 145 series polarization switch is a TE₁₁ mode device with both the input and output in circular waveguide. It is equipped with a standard pin-aligned circular flange similar to most of Mi-Wave’s standard 200 series antenna components . Typical units are continuously adjustable over ±90° of rotation. Please note that the rotation in Faraday rotators is frequency sensitive. The instantaneous bandwidth of these devices is limited to approximately 1% of the center frequency for a fixed drive current value.

Applications

Used primarily in conjunction with the antenna product line, our 145 series polarization switch provides a means of remote controlled polarization change. These switches can be used to align polarization between satellite and ground station communication when the satellite polarization is unknown. They are also useful in the test and measurement of circular TE₁₁ mode components where axial ratio and ellipticity must be calculated.
