Polarization Switches-Series145

Release time：2024-4-25 9:25:51 Add to cart

Mi-Waves’ 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-Waves’ standard 200 series antenna components.

Typical units are continuously adjustable over ±90º 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.
