Description
Rectangular waveguide DPDT latching switch 28WDESMD, operating from 26.5 to 40GHz, has a 0.2dB insertion loss and low VSWR 1.20:1. 28WDESMD covers the WR28 full waveguide band and comes with four flanges FBP320(UBR320). It can handle 110W continuously and 20KW 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.
