Description
Rectangular waveguide SPDT latching switch 90WESMD, operating from 8.2 to 12.4GHz, has a 0.1dB insertion loss and low VSWR 1.10:1. 90WESMD covers the WR90 full waveguide band and comes with three flanges FBP100(UBR100). It can handle 1000W continuously and 250KW peak power. A-INFO offers both E-plane and H-plane waveguide switches. Waveguide switches are all designed with position indicator functions that can give feedback on the waveguide switch position to the control system. The position signal is mechanically controlled and independent of the electric motor circuits, significantly improving the reliability. Waveguide switches can switch signals in the microwave communications system, broadcasting, and radar applications.
